(D) centripetal force​

Answer 1

Answer:

may be b is right ji yyyyy

Answer 2

The moon and the artificial satellites are moving only under the influence of the (B) gravitational field of the earth.

• The earth exerts a gravitational force on the moon and the artificial satellites due to the gravitational field present around it.
• The magnitude of this force is directly proportional to the mass of the earth and the satellite and inversely proportional to the square of the distance between them.
• This attractive force acts as the centripetal force and causes the satellite to revolve around the Earth.
• The escape velocity refers to the minimum required velocity that is needed by an object to exit the gravitational field of the planet.
