question_answer

Wave pulse on a string shown in figure is moving to the right without changing shape. Consider two particles at positions \[{{x}_{1}}=1.5m\] and \[{{x}_{2}}=2.5m\]. Their transverse velocities at the moment shown in figure are along directions

A) Positive y-axis and positive y-axis respectively

B) Negative y-axis and positive y-axis respectively

C) Positive y-axis and negative y-axis respectively

D) Negative y-axis and negative y-axis respectively

Correct Answer: B

Solution :

Dotted shape shows pulse position after a short time interval. Direction of the velocities are decided according to direction of displacements of the particles
