Question

If the mass of a body is 5 kg, what is its weight?

• A. 49N
• B. 5N
• C. 49 kg wt
• D. none of these

Answer 1

The correct option is A 49N

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 surface of earth.

so if $m=5kg$ then $W=m.g=5\times 9.81=49.05N$

so option A is correct.
