Two point charges q(1)=2xx10^(-3) C and ...

Two point charges `q_(1)=2xx10^(-3) C` and `q_(2)=-3xx10^(-6) C` are separated by a distance `x = 10` cm. Find the magnitude and nature of the force between the two charges.

A

4 N

B

5 N

C

9 N

D

13 N

Text Solution

Verified by Experts

The correct Answer is:
C
`F=1/(4piin_(0))xx(q_(1)q_(2))/r^(2)`
`therefore" "F=(9xx10^(9)xx5xx10^(-6)xx2xx10^(-6))/((10xx10^(-2))^(2))=9N`
