QAIPMT-2005-Ph-2544: NEET 2005 Physics - Class 11 AIPMT-2005-Ph-2544 Solution: A drum of radius R and mass M, rolls down without slipping…
A drum of radius R and mass M, rolls down without slipping along an inclined plane of angle . The frictional force
Multiple Choice Options
- A dissipates energy as heat
- B decreases the rotational motion
- C decreases the rotational and translational motion
- D converts translational energy to rotational energy.
Step-by-Step Verified Solution
It is noted that net work done by frictional
force when drum rolls down without slipping is
zero, so W net = 0
W trans + W rotational = 0
_K trans + _K rotational = 0
_K trans = � _K rotational
Hence, frictional force converts translational energy to rotational energy.
