A planet moves around the sun. At a point P it is closest from the sun at a distance d1 and has a velocity V1. AT another point Q, when it is farthest from the sun at a distance d2 its speed will be
Answer & explanation
Correct answer: option 3
Angular momentum is conserved
∴ mv1 d1 = mv1 d2
v2 = $\frac{v_1 d_1}{d_2}$
