Question

A physics textbook of mass m rests flat on a horizontal table of mass M placed on the ground. Let N a → b ​ be the contact force exerted by body "a" on body "b". According to Newton's 3 rd Law, which of the following is an action-reaction pair of forces?

TestHub · Accepted Answer

An action-reaction pair acts between the same two bodies, is equal in magnitude, opposite in direction, and is of the same type.

$N_{ground \to table}$ and $N_{table \to ground}$ form such a pair (option D). The other options pair forces that act on one body or involve different interactions.
