Question

If a person weighs 786 N on earth,his weigth on moon will be_

Answer 1

W=mg

g on earth = 10 N/kg

g on moon = 1.67 N/kg

786 = m × 10

m = 786/10

m = 78.6 kg

Weight on moon = 78.6 × 1.67

W = 131.26 N

Answer 2

Weight on earth =786N                   weight on moon =1/16*weight on earth                                        therefore weight on moon =1/16*786N=4.19N
