Physics Question on Motion in a straight line
If a particle moves in a circle describing equal angles in equal intervals of times, the velocity vector
A
remains constant
B
change in magnitude
C
changed in direction
D
changed both in magnitude and direction
Answer
changed in direction
Explanation
Solution
The figure clearly describes motion of the particles and it is evident that the velocity vector changes direction continuously during the motion. As the particle is covering equal angles in equal time, the magnitude remains constant while the direction changes.
