# Frequent question: At which point does the electric field have the largest magnitude?

Contents

Electric field strength is greatest where the lines are closest together and weakest where lines are furthest apart.

## Which point has the largest magnitude of electric field?

Explanation: E is greatest in magnitude where V changes most rapidly with position (the largest gradient) which is where the lines are closest together.

## In which case does the electric field at the DOT have the largest magnitude?

The electric field is proportional to q and inversely proportional to r. q is the largest in option A. Therefore, Electric field at the dot has largest magnitude in case A. 2.

## Which charge has the largest magnitude?

(b) Charge C has the largest magnitude since maximum number of field lines are associated with it. (c) (i) near A. There is no neutral point between a positive and a negative charge. A neutral point may exist between two like charges.

## What is the magnitude of the electric field at point A?

the magnitude of the electric field (E) produced by a point charge with a charge of magnitude Q, at a point a distance r away from the point charge, is given by the equation E = kQ/r2, where k is a constant with a value of 8.99 x 109 N m2/C2.

## What is the magnitude of the electric field at the origin?

The electric field resulting from a point charge q at the origin has magnitude kq/r² (where k is Coulomb’s constant) and direction away from the origin if q>0.

## What are the magnitude and direction of the electric field?

The electric field direction points straight away from a positive point charge, and straight at a negative point charge. The magnitude of the electric field falls off as 1 / r 2 1/r^2 1/r21, slash, r, squared going away from the point charge.

## What are the units of electric potential difference?

The standard metric unit on electric potential difference is the volt, abbreviated V and named in honor of Alessandro Volta. One Volt is equivalent to one Joule per Coulomb.

## Which of the following represents the electric field lines?

If we have a negative charge, then its electric field lines are radially inward direction as shown in the above figure. Because electric field lines start from infinity where the positive charge is supposed to be existing and end at a negative charge. Thus, option (B) is the correct answer.

## Which of the following represents the electric field lines due to a single positive charge?

The field lines of a single positive charge are radially outward.

## Which of the following statement is not true about electric field lines?

Electric field lines start from positive charge and end at negative charge. Two electric field lines can never cross each other. Electrostatic field lines do not form any closed loops. Electric field lines cannot be taken as continuous curve.

## What is the magnitude of the electric field intensity at a point where a proton experiences an electrostatic force of magnitude 2.30 x10 25 Newton?

What is the magnitude of the electric field intensity at a point where a proton experiences an electrostatic force of magnitude 2.30 x 10-25 newton? 144×10-25.

## What is the magnitude of a point charge which produces an electric field of 2 Newton per Coulomb at a distance of 60cm?

What is the magnitude of a point charge which produces an electric field of 2 NC minus one at a distance of 60 cm? 2×10−12 coulomb.

## What is the magnitude of a point charge due to which the electric field 30cm?

The magnitude of point charge due to which the electric field 30 cm away has the magnitude 2 NC1 will be 2 x 1011 C.
