Select the correct answer.
Which type of energy is thermal energy a form of?
O A. chemical energy
OB. kinetic energy
OC. magnetic energy
OD. potential energy

Kinetic energy

Explanation:

as it is due to the motion of particles, with motion being the key. Thermal energy results in an object or a system having a temperature that can be measured. Thermal energy can be transferred from one object or system to another in the form of heat.

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach
