If a force of 1pN act on a body of mass 5Kg for 1 sec than change in momentum is?

Answer 1

The change in momentum can be calculated using the formula:

Change in momentum = force x time

Here, force = 1pN = 1 × 10^-12 N (since 1pN = 1 × 10^-12 N)

Time = 1 sec

So, the change in momentum = (1 × 10^-12 N) × (1 sec)

= 1 × 10^-12 kg m/s

Therefore, the change in momentum is 1 × 10^-12 kg m/s.
