Question

Two point charges +16 micro coulom and-9 micro coulom are placed 8 cm part in air.calculate the electrostatic force?

Answer 1

Answer:

F = KQq/r^2

K equals to 9 X 10^9

Q is 16 microcoulomb and q is -9 microcoulomb

distance is 8 cm which is converted in meters so 0.08m

now put the formula.....

=9X10^9(16X10^-6)(-9X10^-6)/0.08

now calculate it..
