Assertion-Reason▾

Question

Assertion (Ꭺ)

A particle of mass m strikes a wedge of mass M horizontally as shown in the figure. If collision is perfectly inelastic then, it can be concluded that the particle sticks to the wedge.

Particle of mass m strikes a wedge of mass M horizontally

Particle of Mass M Strikes a Wedge of Mass M Horizontally

In above we figure we show that the triangle, and the particle have mass m and M.

Reason (Ꭱ)

In perfectly inelastic collision velocity of both bodies is same along common normal just after collision.

Choices

Choice (4) Response

a.

Both Ꭺ and Ꭱ are true but Ꭱ is NOT the correct explanation of Ꭺ

b.

Ꭺ is false but Ꭱ is true

c.

Both Ꭺ and Ꭱ are false

d.

Ꭺ is true but Ꭱ is false
