Question
In the above question, the electric force acting on a point charge of 2 C placed at the origin will be :
Options
A.2 N
B.500 N
C.-5 N
D.-500 N
Solution
At origin, E = − 
= − 2.5 V/cm = − 250 V/m
∴ F = force on 2C = q E = 2 × (− 250) N = − 500 N.
= − 2.5 V/cm = − 250 V/m∴ F = force on 2C = q E = 2 × (− 250) N = − 500 N.
