Question

weigh of 2kg of a object is (a) 9.8n (b) 19.6n (c) 29.4n (d) 39.2n​

Answer 1

we know that weight of an object on earth is equal to the product of its mass and acceleration due to gravity

i.e, w=mg

Given, m=2kg

g=9.8m/s^2 (Standard value)

W=mg

=> Weight of the object = (2)(9.8) N

=>weight of the body = 19.6 N

Also, 1N=10^5 dynes

So, Weight in C.G.S = 19.6 X 10^5 dynes

=>weight in C.G.S =1.96 X 10^6 dynes
