Question

-2 What is the weight in Newtons of a 10kg object on the moon and on the earth? ( Take g= 9.8 m/s^2)




90N, 16.3N

98N , 26N

95N, 16.3 N

98N, 16.3N​

Answer 1

Answer:

weight= mass×acceleration due to gravity

mass is given as 10kg

there fore, weight= 10×9.8

weight=98 kg m/s^2 = 98 Newtons

Answer 2

Answer:

Option D is the right choice.

Explanation:

The gravitational pull of earth and moon are different because of difference in their mass and size.

so the acceleration of a body under gravity also differs for moon and earth.

The v gravitational acceleration on Earth is 6 times that of on the moon.

So,

Weight of the given body(of 10kg) on Earth =ma=10×9.8=98N

Weight of the given body on moon=ma/6=10×9.8/6=16.3N

Hence weight of the 10kg body on Earth and moon are 98N and 16.3N respectively.
