Question

A cube of side 10 cm encloses a charge of `0.1 muC` at its center. Calculate the number of lines of force through each face of the cube.
A. `1.113 xx 10^(11)`
B. `1.13 xx 10^(4)`
C. `1.13 xx 10^(9)`
D. 1883

Answer 1

Correct Answer - D
d. `q/(6epsilon_0) = (0.1 xx 10^(-6)) /(6 xx 8.85 xx 10^(-12)) = 1883`.
