Practice question

Question

Which of the following statements is correct about a satellite in circular orbit?

Options

Choose one · Correct answer highlighted

Its speed increases with altitude Gravity provides the centripetal force Correct Its total energy is positive It has no kinetic energy

Explanation

The gravitational force provides the centripetal force (GMEmr2 = mv2r), making option 2 correct. As per NCERT, applying relevant law/formula with correct units and sign convention leads to Gravity provides the centripetal force.
