Question

The weight of a body of mass 6-0 kg on moon is
10 N. If a boy of mass 30 kg goes from earth to
the moon surface, what will be his (a) mass,
(b) weight?
() 30 ko (b) 50 m​

Answer 1

Answer:

the mass always remains constant in a body no matter wherever the body is in the universe.

(unless the body is traveling at a speed of 1/10 of the speed of light or higher)

hence , (a) = 30kg

(b) we know weight/F = ma

so F = 10N

m = 6kg

therefore ,(a) = 10/6 = 1.67m/s²

therefore,

m(2) = 30kg

a = 1.67m/s²

F / weight of the second body = ma

= 30 × 1.67

= 50.1 N (approx)

hope it helped :)
