Question

A car moves in a semicircular track of radius 700 m. If it starts from one end of the track and stops at the other end, the displacement of car is (A) 2200 m (B) 700 m (C) 1400 m (D) none of these.

Tardigrade Admin · Accepted Answer

Displacement = diameter = 2 × radius = 2 × 700 = 1400 m Distance moved in this case is given by (1/2)(2 π r) = π r

Q. A car moves in a semicircular track of radius $700 m$ . If it starts from one end of the track and stops at the other end, the displacement of car is

2200 m

700 m

1400 m

none of these.

Displacement = diameter = 2 $\times$ radius = 2 $\times$ 700 = 1400 m
Distance moved in this case is given by $\frac{1}{2} (2 π r) = π r$
