railway RRB Technician Grade 1 Mock Test 2024 Physics Electric Potential Electric Potential and Electric Potential Energy
A hollow spherical conductor of radius R, placed in air, is given a charge Q. Then the potential at a point inside the conductor and at a distance R/2 from its centre is:
1
\(V=\frac{1}{4 \pi \varepsilon_{0}} \frac{Q}{R}\)
2
\(V=\frac{1}{4 \pi \varepsilon_{0}} \frac{Q}{2 R}\)
3
VC = 4πεR
4
V = 4πε0R
