Question

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

1 ) remain same
2 ) become double
3 ) become half
4 ) become four times​

Answer 1

Answer - Will remain same .

Linear momentum formula

P = mv

so if earlier the mass is 50 and the velocity is 4 then it's linear momentum will be 200 kg • m/s

____________________________

and if the mass is doubled means ( 50 × 2 ) = 100 and the velocity is half ( 4 ÷ 2 ) = 2

then product here will be

= 100 × 2

= 200 kg • m/s
