Question 168: Gravitation

Question

The minimum and maximum distances of a planet revolving around the sun are x1 and x2. If the minimum speed of the planet on its trajectory is v0 then its maximum speed will be :

Accepted Answer

Angular momentum conservation equation $${v_0}{x_2} = {v_1}{x_1}$$
$${v_1} = {{{v_0}{x_2}} \over {{x_1}}}$$

Answer

$${{{v_0}x_1^2} \over {x_2^2}}$$

Answer

$${{{v_0}x_2^2} \over {x_1^2}}$$

Answer

$${{{v_0}x_1^{}} \over {x_2^{}}}$$

Answer

$${{{v_0}x_2^{}} \over {x_1^{}}}$$
