Question

(e) A man weighs 880 N at the equator.
6)
Calculate his mass. (g = 10 m/s-)
(ii) How will his weight change if taken to the poles?​

Answer 1

Explanation:

due to this weight changes

Answer 2

Answer:

88 kg

Increase

Explanation:

At equator:  gravitation acceleration is 10 m/s².  

∴ force(weight) = mg  

    880 = m(10)  

    880/10 = 88 = m(mass)

Mass of the man is 88 kg.  

At the poles: distance from the centre of earth is lesser than that from equator. As g is inversely proportional to the distance, and distance is decreased, it must increase.
