Question

Two identical satellites are at R and 7R away from each surface, the wrong statement is (R - Radius of earth)

  1. ratio of total energy will be 4
  2. ratio of kinetic energy will be 4
  3. ratio of potential energies will be 4
  4. ratio of total energy will be 4 bat ratio of potential and kinetic energies will be 2

The correct answer is: ratio of total energy will be 4 bat ratio of potential and kinetic energies will be 2

A student was asked to prove a statement by induction. He proved
i) P(5) is true and
ii) truth of P(n)rightwards double arrow truth of P(n+1), n element of N.
On the basis of this, he could conclude that P(n) is true
