A metal plate of surface area `2m^(2)` is charged with `sqrt(8.85muC)`. What is the mechanical force acting on the plate if it is kept in air ? [`epsi_(0)=8.85xx10^(-12)C^(2)`]

A

0.5 N

B

2 N

C

1 N

D

1.5 N

Text Solution

Verified by Experts

The correct Answer is:
C
`F=(1)/(2)(6^(2)A)/(epsi_(0)K)=(1)/(2)xx(8.85xx10^(-12))/(8.85xx10^(-12)xx1)xx2=1N`
