Question

The force between two charges separated by
distance I m is 1.8 N. The charges are in ti
ratio 1 : 2 then the charges are
1) 51C,5ục 2) 5uC,10uC
3) ΤμC,10μC
4) 10°C,20uc​

Answer 1

Answer:

F=KQq/r

:. 1.8=9*10^⁹Qq/1

:.1.8/9*10^⁹=Qq

0.2*10^-⁹=Qq

now....

Q/q=1/2....

:.2Q=q........

:. 0.2*10^-⁹=2Q²

:.0.1*10^-⁹=Q²

:.1*10^-⁸=Q²

Taking sqrt onBS

10^-4=Q.........
