Assertion-Reason▾

### 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.

### Reason (Ꭱ)

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

### Choices

Choice (4) Response

a.

Ꭺ is false but Ꭱ is true

b.

Both Ꭺ and Ꭱ are true and Ꭱ is the correct explanation of Ꭺ

c.

Ꭺ is true but Ꭱ is false
