A particle can travel point A to B from two different path 1 and 2, as shown, in same interval of time. Then which of the following is incorrect?

Options

A. Average velocity along the two paths must be equal
B. the particle may travel along both the paths unaccelerated
C. the direction instantaneous velocity along the path 1 and 2 can be same for a maximum of two point on the parths.
D. The average and instantaneous velocity along path 1 can have direction.

Answer

A, C, D

Explanation

The particle cannot have zero acceleration along path 1 ass direction of velocity is charging with time.
Average velocity`=(t otal displacement)/(t otal time taken)=(AB)/(t)`
Hence average velocity is equal along both paths.
Average velocity is along AB, instaneous at P and Q is in same direction.
