Find the weight of a 1 gram object at the earth's surface? With solution |
|
Answer» of an OBJECT on the surface of earth is just the FORCE exerted by the object on earth.We know that F = ma So, Weight = m × a=> weight = m × g (g = acceleration due to gravity)For CALCULATING weight in NEWTON, the mass should be in kg and the acceleration should be in m/s²Given mass = 1 gram = 0.001 kg Taking g as 10 m/s² we get, weight = 0.001 × 10=> weight = 0.01 Newton. Or taking g as 9.8 m/s², we getweight = 0.001 × 9.8=> weight = 0.0098 Newton. |
