Question

When mass of a body is made twice , keeping its velocity unchanged, the linear momentum of the body __________ with respect to its original momentum

a)remains unchanged
b)becomes half
c) becomes one fourth
d) becomes twice

Answer 1

Answer:

Becomes 4 times

Momentum is directly proportional to velocity. If momentum of an object is doubled , but its mass does not increase (so velocity remains below the speed of light) then its velocity is doubled. If the velocity is doubled, then the kinetic energy increases by four times.
