Explanation:
Heat is defined as a form of energy due to temperature difference. Heat is also a measure of the total internal energy of a body.
Heat has the following effects;
1) Heat causes change of state of a body
2) Heat changes the temperature of a body
3) Heat causes expansion of a body
4) Heat may alter certain physical properties of a body such as electrical conductivity, density etc
5) Heat causes a change in the pressure and volume of a body
6) Heat may lead to the emission of electrons from metals(thermionic emission)

The new electrostatic force will be 384 units.
The electrostatic force of attraction between two charges (charge of object 1) and (charge of object 2) separated by a distance d is given by
is the permittivity of free space.
Initially, we have,
Now, if the charge of object 1 is multiplied by 1, the charge of object 2 is multiplied by 3, and the distance separating objects 1 and 2 is divided by 4, we have, .
The new electrostatic force will be,
units.
We have,
Hence,
Hence, the new electrostatic force will be 384 units.
