A boy have a mass of 50 kg. What would be his weight on the Earth? (g = 10 ms−2)
500 N
Weight is the force due to which the Earth attracts all bodies towards its centre. Weight of an object is expressed as, w = mg, where 'm' is the mass of the object and 'g' is the acceleration due to gravity. Therefore w = 50 × 10 = 500 N.
