Question

What is the gravitational field strength at the surface of a planet if a 2, k, g,

2kg basket of shopping weighs 52, N,

52N?

Answer 1

We can find the gravitational field strength at the surface of the planet from the definition of the weight:

$$W=mg,$$ $$g=\dfrac{W}{m}=\dfrac{52\ N}{2\ kg}=26\ \dfrac{N}{kg}.$$
