Question

an object has a body mass of 62 kg on earth.one day it is brought to an unknown planet.when it is measured on a spring balance,its weight is 279N.what is the gravitational force of that planet? a)9.8 n/kg b)7.6 n/kg c)6.4 n/kg 4)4.5 n/kg

Answer 1

Answer: 4.5N/kg

Explanation:

Mass = 62kg

Force = 279 N

solution:

F= mg

279 = 62*g

g=279/62

g= 4.5 N/kg
