Two inclined frictionless tracks, one gradual and the other steep meet at A from where two stones are allowed to slide donw from rest, one of each track as shown in the figure.

A

Both the stones reach the bottom at the same time but not with the same speed.

B

Both the stones reach the bottom with the same speed and stone I reaches the bottom earlier than stone II.

C

Both the stones reach the bottom with the same speed and stone II reaches the bottom earlier than stone I.

D

Both the stones reach the bottom at different tiems and with different speeds.

Two inclined frictionless tracks, one gradual and the other steep meet at A from where two stones are allowed to slide down from rest, one on each track (Fig. 6.16). Will the stones reach the bottom at the same time? Will they reach there with the same speed? Explain. Given 61 = 30^@ , theta_2 = 60^@ , and h= 10 m, what are the speeds and times taken by the two stones ?

A small sphere rolls down without slipping from the top of a track in a vertical plane. The track has an elevated section and a horizontal part is 1.0 m above the ground level and the top of the track is 2.4 m above the ground. Find the distance on the ground with respect to the point B (which is vertically ) below the end of the track as shown in figure. Where the sphere lands. During its flight as a projectile does the sphere continue to rotate about its centre of mass? Explain.

Two insulating infinitely long wires are lying mutually perpendicular to each other as shown in the figure. If the two wires carry currenst I_1 and I_2 as shown in the figure, find the magnetic field at point P (A,b).

When a body slides down from rest along a smooth inclined plane making anangle of 45^@ with the horizontal, it takes time T. when the same body slides down from rest along a rough inclined plane making the same angle and through the same distance, it is seen to take time pT, where p is some number greater than 1. Calculate the co-efficient of friction between the body and the rough plane.
