Question

A body has a mass $Mkg$ on the earth. What will be its weight on the earth?

• A. $Mg$newton
• B. $\frac{M}{g}$ newton
• C. $M$ newton
• D. Zero

Answer 1

The correct option is A

$Mg$newton

1. Weight is the force of gravity with which a body is attracted toward the earth.
2. The weight of the body is given by the formula $W=Mg$, where W is the weight of the body, M is the mass of the body and g is the acceleration due to gravity.
3. The value of acceleration due to gravity on Earth's surface is taken to be $9.8{\mathrm{ms}}^{-2}$.

Hence option A is correct, a body that has a mass of $Mkg$ on earth will weigh $Mg$ newton on earth, as $g$ is the acceleration due to gravity on the surface of the earth.
