The electric potential at a point in free space due to a charge `Q` coulomb is `Q xx 10^(11)` volts. The electric field at that point is

`4 pi in_(0) Q xx 10^(20)` volt/m

`12 pi in _(0) Q xx 10^(22)` volt/m

`4 pi in _(0) Q xx 10^(22)` volt/m

`12 pi in_(0) Q xx 10^(20)` volt/m

Text Solution

Verified by Experts

The correct Answer is:

`V = (1)/(4 pi epsi_(0)) (Q)/(r)`
