Question

What is the mass of an object whose weight is 98 N?

• A. 98 kg
• B. 9.8 kg
• C. 10 kg
• D. none of these

Answer 1

The correct option is C 10 kg

The most common definition of weight is the force exerted on a body by

gravity. This is often expressed in the formula $W=mg$, where 'W' is the

weight, 'm' the mass of the object, and g gravitational acceleration,

$g=9.81$ on the surface of the earth.

so if $W=98N$ then $m=\frac{W}{g}=\frac{98}{9.81}=10kg$

Hence, option C is correct.
