MCQ

A sphere is rolled on a rough horizontal surface. It gradually slows down and stops. The force of friction tries to:

Decrease the linear velocity.
Increase the angular velocity.
Increase the linear momentum.
Decrease the angular velocity.

✓
$A$ and $B$
B
$B$ and $C$
C
$A$ and $D$
D
$B$ and $D$

✓

Answer

Correct option: A.

$A$ and $B$

If a sphere is rolled on a rough horizontal surface, the force of friction tries to oppose the linear motion and favours the angular motion.
