a force acting on a particle of mass 200g displaces it through 400cm in 2s. find the magnitude of force if the initial velocity of the particle is zero Share with your friends Share 0 Apurba Paul answered this If the initial velocity of the particle is zero then acceleration isa=2st2Here s=400 cm=4 m and t=2 s. So we havea=2×422=2Now mass m=200 g = 0.2 kg. So force f=ma=0.2×2=0.4 N 4 View Full Answer Shambhavi Jha answered this u = 0 t = 2s m = 200g = 0.5 kg s= 400cm= 4 m s= ut + 1/2× at^2 4 = 0 + 1/2 × a × 2×2 4= 2a a = 2 m/s^2 F = ma F = 0.5 kg × 2 m/s^2 F = 1 N -5
