Question

Two positive point charges of 12uc and Suc

respectively are 10cm apart in vacuum. Calculate
the force between them.​

Answer 1

54 N

Step-by-step explanation:

We have two positive charges 12uC and 5 uC ,they are kept at a distance of 10cm.

We have a relation for force between two charges q1,q2 as

`F=(kq1q2)/(r^(2) )`

Value of k is
`9*10^9`

On substituting the values into the equation we get,

`F=(9*10^9*12*5)/(10^9*10)\\\\  F=54N`

Hence the force between them is 54 N.
