Question

The kinetic energy , potential energy and total energy of a satellite is in the ratio

(a)  1 : 1 : 2

(b)  1 : -1 : 2

(c)  1 : -2 : -1

(d)  1 : -1 : -2​

Answer 1

Answer:

The correct answer is

a) 1 : 1 : 2

Answer 2

The kinetic energy , potential energy and total energy of a satellite is in the ratio of 1 : 1 : 2

${}$

Explanation

• The total energy of a satellite is just the sum of its gravitational potential and kinetic energies.
• the ratio of the kinetic energy to the total energy of the electron in a quantum state n is k in Bohr model.
• Formula of Kinetic energy in orbit = ½ mv2 = + ½GMm/r
• formula of Total energy of satellite in orbit = -GMm/2r.
