1 of 1

Application +4 | -1

A point charge q produces an electric field of magnitude

2\mathrm{ }N{C^{ - 1}}

at a point distance 0.25 m from it. What is the value of charge?

View answer and explanation

Correct option: A

1.39

\times {10^{ - 11\;}}

C

Option A (1.39

\times {10^{ - 11\;}}

C) is correct because it is calculated using the formula for electric field due to a point charge.

Assertion:- Electric field lines do not cut at any point.
Reason:- At any point, there is only one direction of electric field. Statement-I: A positive point charge is brought in an electric field, the electric field at neary by point will increase

Statement-II: Electric field produced by charge may favour the existing electric filed Two particles having equal mass and charge
are separated by a distance
