What is the mass of an object whose weight is 49 newtons?

Options

A. 5 kg
B. 6 kg
C. 7 kg
D. 8 kg

Answer

A

Explanation

Here Weight W=49 N
Mass m= ? (to be calculated )
And ,Acceleration due to gravity `g=9.8 m//s^(2)`
Now ,putting these values isn the formula
`W =mxxg`
we get `89 =mxx 9.8`
`m=49/9.8`
m= 5 kg
thus mass of the object is 5 kilograms
