Question

The mass of an object is 10 kg, its weight on the earth is

• A. 9.8 N
• B. 8.9 N
• C. 89.0 N
• D. 98.0 N

Answer 1

The correct option is D

98.0 N

Given data

The mass of the object, $m=10kg$.

Finding the weight

As we know that the weight (w) of the body is the product of mass (m) and acceleration due to gravity (g).

$w=mg$

Assuming, $g=9.8\frac{m}{s^2}$

$w=10\times 9.8kg\frac{m}{s^2}$

$w=98.0N$

Thus, the correct answer is (d).
