Question

Pls give the answer of the question

Answer 1

Answer:

IS IT OPTION 3

Explanation:

Answer 2

Electric field(E) due to surface charge density =

$\frac{surface \: charge \: density}{epsilon}$

= 4*10^-6/8.85*10^-12

now force on charge of -2*10^-6 C

Force = q*E

= (2*10^-6*4*10^-6)/8.85*10^-12

= 8/8.85

= 0.9 N

option "B"
