A uniformly charged conducting sphere of 2.4 ~m diameter has a surface charge density of 80.0 C m ⁻² . The charge on the sphere is nearly
Options
- A2.5 10⁻³ C
- B1.45 10⁻³ C
- C6.5 10⁻³ C
- D0.15 10⁻³ C
Correct answer
B. 1.45 10⁻³ C
Step-by-step solution
Diameter of sphere d =2.4 ~m Radius, r = d 2 =1.2 ~m Surface charge density, =80 10⁻⁶ C m ⁻² Charge on the sphere, Q = A aligned & = (4 r ^2 ) & =80 10⁻⁶ 3.14 (1.2)^2=1.45 10⁻³ C aligned
