Newtons 3rd law
Force required = rate of change in momentum of the gun
F = (20/1000) * 10 * 500 = 100 N
Hope this helps !!

F = nmv/t
= (n/t) × mv
= [20 /s] × 20 × 10^-3 kg × 500 m/s
= 200 N
200 N force is required to hold the gun.
= (n/t) × mv
= [20 /s] × 20 × 10^-3 kg × 500 m/s
= 200 N
200 N force is required to hold the gun.
