The tension in the string is an example of the electromagnetic force.
A. true
B. false

Hint: Force is a vector and it follows vector’s law of addition. There are two laws of adding vectors which are mostly used. These are Triangles law of vector addition and parallelogram’s law of vector addition.

Complete step by step answer:
The tension origin is due to the existence of the string and the load attached to it. If we remove the load attached then tension ceases to exist and thus it is not an electromagnetic force. Electromagnetic forces come in to play when we are dealing with the electrical charges and here there are no charges. So, the given statement is FALSE.

So, the correct answer is “Option B”.

Additional Information:
These electromagnetic waves have their importance and are widely used in our everyday life. Radio waves are used in communications and telecommunications. They are also used in strategic military communications. Microwaves are also called heating waves and they are used in microwave ovens. Gamma rays are harmful rays and they cause blood cancer in human beings. X-rays are used in diagnosis in drawing the picture of a human's internal organs as they get deflected by the bones but not by the mass.

Note:
Tension is a force and is measured in Newtons, the electromagnetic force is also measured in Newtons. The electromagnetic force is a kind of non-contact force while the tension is a type of contact force. Tension has its origin in relation to the force of gravity.
