Question

- The weight of an object having mass 5kg is 450 N weight of another object having mass 50kg is 147N. Check weather the mass and we weight are proportional What is the constant of proportionality​

Answer 1

see below

Explanation:

We are here given that weight of an object having mass of 5kg is 450N .

As we know that,

Weight = mass * acceleration due to gravity (g)

So that ,

450N = g * 5kg

g = 450/5 m/s²

g = 90m/s²

Again in second case,

147N = g' * 50kg

g' = 147/50 m/s²

g' = 29.4 m/s²

since here g ≠ g'

Therefore,

mass and weight are not promotional in this case. This may be due to the fact that the acceleration due to gravitational force of each celestial object is different and weights may have been measured on different planets.

And the constant of proportionality is g ( acceleration due to the gravitational force) .

And we are done!
