Question

if the weight of a body on the surface of earth is 42 N. what will be its weight on moon​

Answer 1

Explanation:

weight of an object on moon is 1/6 of the it's weight on earth.

so, in this case -

$\frac{1}{6} \times 42$

= 7 kg

hope it helps !!

Answer 2

Answer:

42 only. no changes, Same mass as on Earth.

Explanation:

Well, the kg is a unit of mass, not weight. So on the moon your mass is unchanged. Weight is mass x force, in this case the force of gravity expressed as meters per second squared. On Earth the force of gravity is about 9.8 m/s^2. 42 kg mass on Earth has a force due to gravity, weight, of approximately 411.6 Newtons. On the moon the force of gravity is about 1.6 m/s^2, so your force due to gravity on the moon is about 67 newtons. Your mass is still 42 kg.

One way to think about this is to imagine a beach ball and a bowling ball floating in space. Both are weightless. That is to say there is no force of gravity acting on them. But the mass is unchanged. Were you to kick the beach ball it would fly off into space, it has little mass. If you kick the bowling ball, you would hurt your toe. It has great mass.Kilograms is a measure of mass, not weight. A 42 kg mass on earth is a 42 kig mass everywhere.

Weight would be measured in newtons. w= mg , so a mass of 1 kilogram at earth’s surface would have a weight, w in newtons of 1kg*9.8 meters/sec/sec= 9.8 newtons.

Your 42 kg mass would have a weight on earth of 42*9.8=411.6 newtons.

hope it helps u :)

it took me so much time to type the calculations.

please mark me as brainliest.

Doing a websearch, I see that the acceleration of gravity on the moon averages about 1.62 meters/sec/sec, so 42 kg mass would have an average weight of

42kg*1.62 meters/sec/sec =68.04 kg meters/sec/sec= 68.04 newtons.
