JEE Main 8 April 2023, Shift 1, Physics Q35

Question 35 of 90 in this shift, Physics question 5 of 30, Section A.

Given below are two statements: Statement I: If E be the total energy of a satellite moving around the earth, then its potential energy will be E2\frac{E}{2}. Statement II: The kinetic energy of a satellite revolving in an orbit is equal to the half the magnitude of total energy E. In the light of the above statements, choose the most appropriate answer from the options given below
  1. (1)Both Statement I and Statement II are correct
  2. (2)Both Statement I and Statement II are incorrectOfficial answer
  3. (3)Statement I is correct but Statement II is incorrect
