In 1.0 s, a particle goes from point A to point B, moving in a semicircle of radius 1.0 m (see figure). The magnitude of the average velocity is
Step 1: Given that:
A particle goes from point A to B on the semicircular path.
Radius of the path(r) = 1.0m
Time taken(t) = 1sec
Step 2: calculation of the average velocity of the particle:
Average velocity = TotaldisplacementToaltimetaken
Total displacement= Shortest distance between initial and final point
= Diameter of the semicircle
Average velocity= 2m1sec
Option B) 2ms−1 is the correct option.
