Your question: What are the strength and direction of an electric field that will balance the weight of a proton?

What is the electric field that will balance the weight of an electron?

What are the magnitude and direction of the electric field that will balance the weight of the following? For an electron/proton we use the equation qE=mg. Therefore the answer for magnitude would just to multiply the mass of an electron/proton by 9.8.

What are the strength and direction of the electric field?

Because an electric field has both magnitude and direction, the direction of the force on a positive charge is chosen arbitrarily as the direction of the electric field. Because positive charges repel each other, the electric field around an isolated positive charge is oriented radially outward.

What is the magnitude and direction of an electric field that will balance?

As the direction of electric force on negatively charged particle is opposite to the direction of electric field, the direction electric filed is downward. Hence, the magnitude of electric field is and direction is downwards. Chapter 23, Problem 23P is solved.

How is the direction of the force and electric field determined?

Electric field is defined as the electric force per unit charge. The direction of the field is taken to be the direction of the force it would exert on a positive test charge. The electric field is radially outward from a positive charge and radially in toward a negative point charge.

What is the orientation of an electric dipole in a uniform?

-The dipole is in stable equilibrium when it is aligned parallel to the electric field (i.e. the angle between the dipole moment and the electric field is 0∘).

How heavy is a proton?

proton, stable subatomic particle that has a positive charge equal in magnitude to a unit of electron charge and a rest mass of 1.67262 × 1027 kg, which is 1,836 times the mass of an electron.

How do you find the strength of an electric field?

The strength of an electric field E at any point may be defined as the electric, or Coulomb, force F exerted per unit positive electric charge q at that point, or simply E = F/q.

What is electric field direction?

The direction of an electrical field at a point is the same as the direction of the electrical force acting on a positive test charge at that point.

What influences the strength of an electric field?

The electric field strength is dependent upon the quantity of charge on the source charge (Q) and the distance of separation (d) from the source charge.

What is the angle of electric dipole moment?

Dipole moment and electric field are opposite to each other on equatorial line. Hence the angle between them is 180 degrees.

Does Gauss law holds good if Coulomb’s force is inversely proportional to r3?

Gauss’s law which happens to be an equivalent of Coulomb’s law will not hold true if, Coulomb’s law involved 1/r3 dependance instead of 1/r2 dependance. Two charges 2μC and –2μC are placed at points A and B, 6 cm apart. … i.e., the plane normal to AB and passing through its mid-point has zero potential everywhere.

What is the charge of an electron in Kollam?

electron charge, (symbol e), fundamental physical constant expressing the naturally occurring unit of electric charge, equal to 1.602176634 × 1019 coulomb.

How is the strength of an electric field indicated with field lines?

The strength (magnitude) of the electric field is indicated by the number of electric field lines in a region – lots of closely spaced lines means a strong electric field, a few widely spaced lines means a weak electric field. The magnitude of the electric field is proportional to the number of electric field lines.

What is the direction of the electric field at position of the DOT due to the negative point charge as shown?

Electric Field due to positive charge is directed outwards, while due to negative charge is inwards. The Net electric field at a point due to multiple charges is calculated by vector addition of fields due to every individual positive and negative charges.
