Question

Find the weight of a 2 g (=0.002 kg) computer chip. The acceleration due to gravity at the surface of Earth is 9.8 m/s^2.

Answer 1

Answer: 0.0196 Newtons (0.0196N)

Explanation:

Weight is the test mass multiplied by the gravitational field created from the source mass. The source mass is the Earth, and the test mass is the computer chip:

$W=mg$

$W=(0.002kg)(9.8m/s^2)$

$W=0.0196N$
