If a pair of shoes weighs 11.55 newtonson jupiter and 0.3 newtons pluto what does the pair of shoes weigh on earth

If a pair of shoes weighs 11.55 newtons on Jupiter and 0.3 newtons Pluto will weigh 4.56 N and 0.5 N on earth respectively.

The value of gravity on other planets is different as compare to the value of g on earth. For Jupiter it is 2.528 time greater than earth and on Pluto it is 0.06 times lesser than earth. So it can be calculated as follows

Weight on Earth:Weight on Jupiter

1         :  2.528

x         :  11.55

By cross multiplication

1 x 11.55 = X x 2.528

11.55 / 2.528 = x

x = 4.56

So it will weigh 4.56 N on earth

Similarly solving for Pluto

Weight on Earth:Weight on Pluto

1          :  0.06

x          :  0.03

By cross multiplication

1 x 0.03 = X x 0.06

0.03 / 0.06 = x

x = 0.5

So it will weigh 0.5 N on earth

a.   mass number from atomic number

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
