Question

When the sphere makes a complete revolution around its circular path, does it spend:_______

a. more time in the top half of the circle.
b. more time in the bottom half of the circle.
c. the same amount of time in both halves of the circle

Answer 1

Answer:

Explanation:

the same amount of time in both halves of the circle

Answer 2

The sphere will take equal time in traversing the entire circle. Hence, option (c) is correct.

Given data:

The sphere makes a complete revolution around a circular path.

When a sphere revolves around a circular path, then the time period of orbiting is given as,

$t = \dfrac{2 \pi r}{v}$

Here,

r is the radial distance.

v is the speed of sphere.

Since, the time taken by the sphere to revolve around a circular path is dependent on the radius and velocity only. So, it will take the same amount of time in both the halves of circle.

Thus, we can conclude that the sphere will take equal time in traversing the entire circle. Hence, option (c) is correct.
