JEE Main 2022 — Electrostatics Question with Solution

JEE Main 2022 (29 Jun Shift 2)

Question

If the electric potential at any point x, y, z m in space is given by V=3x2 volt. The electric field at the point 1, 0, 3 m will be :

Choose an option

Show full solutionCorrect option: C
Correct answer
C6 Vm-1, directed along negative x-axis.

Step-by-step explanation

Electric potential V=3x2

Electric potential and electric field are related as E=-dVdx=-6x.

At the point 1, 0, 3 m, 

⇒E=-6×1=-6 V m-1

Thus, electric field is 6 V m-1 along negative x‐ axis.
