Q:

A disk and a sphere of same radius but different masses roll on two inclined planes of the same altitude and length. Which one of the two objects gets to the bottom of the plane first ?

A) Depends on their masses	B) Sphere
C) Disk	D) Both reach at the same time

Answer & Explanation Answer: B) Sphere

Explanation:

Time does not depend on mass, else

$T \infty \sqrt{(1 + \frac{k^{2}}{R^{2}})}$

$\frac{k^{2}}{R^{2}}$ => is least for 'sphere' and

hence least time is taken by sphere.

A) 34.76 years	B) 32.48 years
C) 33.31 years	D) 31.68 years

Answer & Explanation Answer: D) 31.68 years

1 day = 24 hours

1 hour = 60 minutes

1 minute = 60 seconds

=> 1 Year = 365.25 x 24 x 60 x 60 Seconds

But 1 billion seconds = ?

1 Year = 365.25 x 24 x 60 x 60 Seconds

? = 1000000000 Seconds

$? = \frac{1000000000}{365.25 x 24 x 60 x 60} years$ = 31. 68 years.
