Question

The linear momentum of an object remains the same if :-

a)both mass and velocity is doubled.

b)mass is doubled and velocity is halved.

c)mass is halved and velocity is doubled.

d)both mass and velocity are halved
(MULTIPLE CORRECT)

Answer 1

Answer:

B and C

Linear Momentum =m*v

a) p=(2m*2v)=4mv

b) p=(2m*v/2)=mv

c) p=(m/2*2v)=mv

d)p=(m/2*v/2)=mv/4

Cheers!

Answer 2

Concept introduction:

Linear momentum, often known as translational momentum or simply momentum, is the resultant of an object's mass and velocity in Newtonian physics. It's a two-dimensional vector quantity with a magnitude and a direction.

Given:

Here a question has been given to us about linear momentum.

To find:

We have to find the correct options from the given options.

Solution:

According to the question, linear momentum $=m*v$.

∴

$b) P_1=2m*\frac{v}{2} =m*v\\c) P_2=\frac{m}{2} *2v=m*v$

Final answer:

Hence, the final answer of the question is options-> $(b) and (c)$.
