Question

An object of mass 1kg and weight 1.67N on moon . Calculate its weight and mass on earth .(g=10m/s^ ,g moon =1/6g earth.)

Answer 1

mass of object=1kg
weight on moon =1.67N
weight on earth=
$\frac{1}{6} \times 1.67n = 27.83kg$
(approx)=28kg
mass on earth=10 into 1 = 10N

Answer 2

m*g(on moon) = 1.67N

g(on moon)=g(on earth)/6

m*g(on earth)/6 = 1.67

weight on earth = 1.67 ×6

=10.02 N

mass on earth = 1 Kg
