Question

Assertion : The forces of action and reaction always appear due to actual physical contact of two bodies.
Reason : A particle can move only under the action of a force.
a) Both A and R are correct and A is the correct explanation of R
b) Both A and R are correct but A is not the correct explanation of R
c) A is true but R is false
d) Both A and R are false

Answer 1

OPTION A ....

Explanation:

b) Both A and R are correct but A is not the correct explanation of R

Because of Newton's third law of motion that Every action has an equivalent reaction that is opposite in direction means force always comes in pair and According to Newton's first law every object will remain at rest or in uniform motion in a straight line unless an external force is applied that means A particle can move only under the action of a force. so Both A and R are correct but they are not supporting each other
