A 100 g block is connected to a horizontal massless spring of force constant 25.6(N)/(m) As shown in Fig. the block is free to oscillate on a horizontal frictionless surface. The block is displaced 3 cm from the equilibrium position and , at t=0 , it is released from rest at x=0 It executes simple harmonic motion with the postive x-direction indecated in Fig. The position time (x-t) graph of motion of the block is as shown in Fig. Velocity of the block as a function of time can be expressed as

Two infinitely long straight parallel wire are 5 m apart, perpendicular to the plane of paper. One of the wires, as it passes perpendicular to the plane of paper, intersects it at A and carries current I in the downward direction. The other wire intersects the plane of paper at point B and carries current k int the outward direction O in the plane of paper as shown in Fig. With x and y axis shown, magnetic induction at O in the component form can be expressed as

A small metal sphere, carrying a net charge q_1 = -2 mu C , is held in a stationary position by insulating supports. A second small metal sphere, with a net charge of q_2 = -8 mu C and mass 1.50 g , is projected toward q_1 . When the two spheres are 0.800 m apart, q_2 is moving toward q_1 with speed 20 ms^-1 as shown in (Fig. 3.151). Assume that the two spheres can be treated as point charges. You can ignore the force of gravity. . How close does q_2 get to q_1 ?
