Which proportionality does kepler’s third law describe? t2 d t d t3 d2 t2 d3

The correct answer is: D

The correct answer to the question is .

EXPLANATION:

As per Kepler's third law on planetary motion, the square of time period of rotation of a planet around sun is directly proportional to the cube of semi major axis.This law is also called as harmonic law.

Let us consider a planet which is revolving around sun in an elliptical orbit.

Let R is the semi major axis of this elliptical orbit and T is the time period rotation of the planet around the sun.

As per Kepler's law, time period and semi major axis are related as -

electric field is a function of 1/r^2

yes, the force per unit charge for a point charge is inverse square law.
