Questions
If a cube of side 5 cm has a change of 6 microculombs, then the surface charge density is
a
4×102μC/m2
b
4×102C/m2
c
4×103 μC/m2
d
4×103 C/m2
detailed solution
Correct option is A
Here, q=6 μC, L=5cm=120m. Area of 6 facesof the cube =6 L2Surface charge density =q6 L2=66(1/20)2 =4×102μC/m2Talk to our academic expert!
