Q. 25.0( 1 Vote )

Correct the mistakes, if any, in the following statements.

i) One newton is the force that produces an acceleration of 1 ms-2 in an object of 1 gram mass.

ii) Action and reaction always act on the same body.

Answer :

(i) One newton is the force that produces an acceleration of 1 ms-2 in an object of 1 kilogram mass, not gram. This is by definition.

(ii)Action and reaction don’t act on the same body. If there are 2 bodies A and B, if A exerts a force(action) on B, B will exert an equal and opposite force(reaction) on A according to Newton’s third law.
