JEE PHYSICS MCQ: ELECTRIC FIELDS AND CHARGES

1 Medium

1 of 1

Application +4 | -1

In a region, the potential is represented by

V(x, y, z)=6 x-8 x y-8 y+6 y z,

where

V

is in volts and

x, y, z

are in metres. The electric force experienced by a charge of

2 \mathrm{~C}

situated at point

(1,1,1)

is

View answer and explanation

Correct option: D

4 \sqrt{35} \mathrm{~N}

Option D (

4 \sqrt{35}

N) is correct because the electric force is calculated by finding the electric field components and then using

F = qE

.

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
