A conducting sphere of radius R is charged to a potential of V volt. Then the electric field at a distance r( R) from the centre of sphere would be :
Options
- AR V r^2
- BV r
- Cr V R^2
- DR^2 V r^3
Correct answer
A. R V r^2
Step-by-step solution
aligned & A s V= q 4 ₀ R & q 4 ₀ =V R and E= q 4 ₀ r^2 & E= V R r^2 aligned
