Question

Compare magnitude electrical and gravitational forces exested on an object mass=10g , charge=20sec by an identical object that is placed 10cm from the first object?

Answer 1

`(F1)/(F2)`=5.4*
`10^(26)`

Step-by-step explanation:

Let

F1=Electric force

F2=Gravitational Force

F1=
`(kq^(2) )/(r^(2) )`

F2=
`(Gm^(2) )/(r^(2) )`

`(F1)/(F2)` =
`((kq^(2) )/(r^(2) ) )/((Gm^(2) )/(r^(2) ) )`

`(F1)/(F2)` =
`(kq^(2) )/(Gm^(2) )`

`(F1)/(F2)` =
`(9*10^(9)*(20)^(2) )/(6.67*10^(-11) *(0.01)^(2) )`

`(F1)/(F2)` = 5.4*
`10^(26)`
