MHT CET 2024 Physics question
A uniformly charged conducting sphere of diameter 14 cm has surface charge density of 40 C m. The total electric flux leaving the surface of the sphere is nearly (Permittivity of free space = 8.85 X SI unit)
Answer: (D)
Solution
By Gauss's law the total flux leaving a closed surface is , where . The radius is cm m. Surface area m. Charge
