The weight of two bodies are 2.0 N and 2.0 kgf respectively. What is the mass of each body ?
mg = 2.0 N
m = 2.0N/10ms-2 = 0.2 kg.
2.0 kgf = 2.0 × g N
m = (2.0 × g N)/ g = 2.0 kg.
Two bodies A and B having mass 2 kg and 4 kg respectively, are separated by 2 meters. Where should a body of mass 1 kg be placed so that the gravitational force in this body due to bodies A and B is zero
