Question

Write the approximate weight of a body of
5 kg. What assumption have you made ?
Ans. 50 N (Assumption : 3 = 10 ms2)
​

Answer 1

Explanation:

Our weight is the product of of our mass and the value of acceleration due to gravity(gravitational force) which is always exerted downwards.

The value of gravitational force is actually 9.8m/s^2 but is rounded off to 10m/s^2 in some cases( this is the assumption you asked).

given that mass is 5 Kg. Weight should be actually - 5*9.8 = 49 kgm/s^2 = 49N, but as we have rounded off gravitational force as 10m/s^2, approximate weight is :-- 5*10 = 50 N. So it's your answer

Please mark as brainliest if it is helpful. Thank you.

Answer 2

Answer:50 N

Explanation:because g=9.8m/s so ,5kg *9.8m/s= 50 kg m/s or 50N
