Question

The orbital speed of jupiter, is (A) equal to the orbital speed of earth (B) greater than the orbital speed of earth (C) proportional to the distance from the earth (D) less than the orbital speed of earth

Tardigrade Admin · Accepted Answer

Orbital velocity (v0)=√(GM/r) propto (1/r) (where r is the distance from sun). Since the distance of jupiter from the sun is greater than the distance between the sun and the earth, therefore orbital speed of jupiter is less than the orbital speed of earth.

Q. The orbital speed of jupiter, is

equal to the orbital speed of earth

greater than the orbital speed of earth

proportional to the distance from the earth

less than the orbital speed of earth

Orbital velocity $(v_{0}) = \frac{GM}{r} \propto \frac{1}{r}$ (where r is the distance from sun).
Since the distance of jupiter from the sun is greater than the distance between the sun and the earth,
therefore orbital speed of jupiter is less than the orbital speed of earth.

Orbital velocity (v0​)=rGM​​∝r1​ (where r is the distance from sun). Since the distance of jupiter from the sun is greater than the distance between the sun and the earth, therefore orbital speed of jupiter is less than the orbital speed of earth.
