nx 1. A wave given by equation y = 1mm sin -5nt is produced in a string 100m long of mass 1 kg. 30 2. 3. What is the tension (in N) in string? x is in m & t in sec. You are trying to construct a compound microscope given two lenses with focal lengths f = 1.0cm and f = 4.0cm. How far apart (in cm) should you place the lenses in order to obtain an angular magnification of 60? (Assume normal adjustment of microscope) A small elastic ball of mass m is placed at the apex of a 45 inclined plane as shown in the figure below. The ball is allowed to slip without friction down the plane (along the dotted line), hit the ground (as shown) and bounce along it. If the height of the inclined plane is h and the coefficient of restitution between the ball and the ground is 0.5, then the distance AB, as marked on the figure, will be N xh, where N is 4. 5. An electron moves in the field produced by a charged sphere of radius 10cm along the radius connecting the points separated by 12 and 15 cm from the centre of the sphere. The velocity of the electron changes thereby from 2x 10 to 2 x 10 m/s. Determine the surface charge (in nc/m) density of the sphere. (Mass of electron = 9.1 103 kg) In the circuit in figure we have = = 100V, R = 20, R = 102, R3 = 40 and R = 302. Find the reading of the ammeter (in A). Disregard the resistance of the battery and the ammeter. A R. R R R nx 1. A wave given by equation y = 1mm sin -5nt is produced in a string 100m long of mass 1 kg. 30 2. 3.
