Two spherical objects with a mass of 6.22 kg each are placed at a distance of 1.02 m apart. how many electrons need to leave each object so that the net force between them becomes zero?

The number of electrons need to leave each object is

Explanation:

Given that,

Mass of object = 6.22 kg

Distance = 1.02 m

We need to calculate the number of electron

Using formula of electric force

....(I)

We know that,

Put the value of q in equation (I)

.....(II)

Using gravitational force

.....(III)

Equating equation (II) and (III)

....(IV)

Put the value in the equation(IV)

Hence, The number of electrons need to leave each object is
