 Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The net force due to different charges around a single charge can be determined using superposition principle. True or False?
 A True B False C Either A or B D None of the above
Explanation:

Detailed explanation-1: -The principle of superposition states that when a number of charges are interacting, the net electrostatic force a given charge is the vector sum of the forces exerted on it due to all other charges. The force between two charges is not affected by the presence of other charges.

Detailed explanation-2: -The formula is given by F=k|q1||q2|r2 F = k | q 1 | | q 2 | r 2, where F is the magnitude of the force between the charged particles, k is the Coulombâ€™s constant, q1 and q2 q 1 and q 2 are the charges on the two particles, and r is the distance between the two particles.

Detailed explanation-3: -The superposition principle (also known as superposition property) states that: for all linear systems, the net response at a given place and time caused by two or more stimuli is the sum of the responses which would have been caused by each stimulus individually. For Coulombâ€™s law, the stimuli are forces.
