Three particles, located initially on the vertices of an equilateral triangle of side $L,$ start moving with a constant tangential acceleration towards each other in a cyclic manner, forming spiral loci that coverage at the centroid of the triangle. The length of one such spiral locus will be
If position time graph of a particle is sine curve as shown, what will be its velocity-time graph.
Velocity-time graph for a car is semicircle as shown here. Which of the following is correct :
An observer moves with a constant speed along the line joining two stationary objects. He will observe that the two objects
The figure shows a velocity-time graph of a particle moving along a straight line The maximum displacement of the particle is ........ $m$
