Two 1.1 kg masses are 1 m apart (center to center) on a frictionless table. each has +10 jc of charge. what is the initial acceleration (in m/s2) of this massif it is released and allowed to move?

The initial acceleration of the mass, if it is released and allowed to move =

Explanation:

Given:

There are two forces that will act on these objects:

The gravitational force between two masses and , separated by distance is given by

where,

G is the Universal Gravitational constant, having value =

Therefore, the gravitational force between these masses is

The electrostatic force between two charges and , separated by distance is given by

where,

k is the Coulomb's constant, having value =

Therefore, the electrostatic force between these masses is

Since, one force is attractive and another is repulsive, therefore, the net force that one mass exerts on another is given by

According to Newton's second law of motion,

It is the acceleration with which the mass starts to move.
