A spherical conductor of diameter 6 ~mm is kept in uniform electric field of intensity 2 10^7 ~N / C . The maximum charge on the conductor is [ 1 4 ₀ =9 10^9 . SI units ]
Options
- A0.2 C
- B2 C
- C20 C
- D0.02 C
Correct answer
D. 0.02 C
Step-by-step solution
Maximum charge on the conductor is: aligned & Q_ max =4 ₀ R^2 E & Q_ max = 1 (9 10^9 Nm ^2 C ) (3 10⁻³ )^2 (2 10^7 N C ) & =2 10⁻⁸=0.02 C aligned
