The correct option is (A). The velocity-time graph for a body that starts from rest and moves with a constant acceleration is a straight line that passes through the origin. The graph shows a linear relationship between velocity and time, indicating constant acceleration.

A wire of 60 cm length and mass 10 g is suspended by a pair of flexible leads in a magnetic field of 0.60 T as shown in the figure. The magnitude of the current required to remove the tension in the supporting leads is:
