Sneha has to lift a load of mass 50 kg to a height 1 m. She can exert – InterviewSolution

1.	Sneha has to lift a load of mass 50 kg to a height 1 m. She can exert a maximum effort of 250 N, so she uses an inclined plane to lift the load up. What should be the minimum length of the plank used by her? (take g = 10 N/kg)
