Question

In which of the following cases, the distance moved and the magnitude of displacement are not equal?
(A) The pendulum is moving to and fro.
(B) If a cycle moves on a straight road in a particular direction.
(C) A cyclist moves on a circular path.
(D) A mosquito flies in a room.

Answer 1

here we have 3 conditions in which the distance moved and the magnitude of displacement are not equal that is
1.when pendulum moves to and fro
2. A cyclist moves in circular path
3. A mosquito flies in a room

in 1and 2 start and end point is same so displacement will be zero, and in 3 displacement will be much shorter as compared to distance.
