Question

A body is at rest on the surface of the Earth. Which of the following statements is correct?
a) No Force is acting on the body
b) Only weight of the body acts on it
c) Net downward force is equal to the net upward force
d) None of these

Answer 1

Net downward force is equal to the net upward force

Answer 2

Answer:

The Option “C” is the correct statement by the given options.

Explanation:

• The Earth is moving. But we can disregard that since the object is at rest. No Earth forces are shifting.
• Gravity from the Earth is one of the ‘most important forces’ acting on the object.
• Other objects in the ‘solar system’ also exert ‘gravitational force’, but this is hardly measurable and in most cases can be ignored.
• So down Earth's gravity, up Earth's electro-magnetism phenomenon. Ignore other forces because they don't matter.
