Question

Question 9.

If the mass of a body is doubled and its velocity becomes half, then the linear momentum of the

body will

(a) remain same

(b) become double

(c) become half

(d) become four times.​

Answer 1

Answer:

Option A) remain same is the correct answer

as

We know

Momentum=mass×velocity

If Mass=m, Velocity=v

And momentum=p

P=mv

given mass is doubled,that is 2m

and velocity is halved ,that is 1/2•v=v/2

therefore

P=2m×v/2

cancelling both 2

p=m×v

Therefore it remains the same

Answer 2

Answer:

it is very easy

Explanation:

the linear momentum remain same

because,according to question

we get p=2M×V/2

THEN ALSO P=MV

THAT S WHY ANSWER IS

REMAIN SAME
