![]() Magnification of a compound microscope is 30. After contact, (a) charge on each is zero (b) charge on each is same but non-zero (c) charge on each is different but non-zero (d) none of these. Then positive plate of one is connected to the negative plate of the other, and negative plate of one is connected to the positive plate of the other. Across each of two capacitors of capacitance 1 |iF and 4 [J.F, a potential difference of 10 V is applied. The difference between the kinetic energies at its highest and lowest position is (a) 20 J (b) 10 J (c) 475 JĤ. A body of mass 1 kg is moving in a vertical circular path of radius 1 m. If after collision both stick together, their speed after collision would be (a) vģ. A body of mass m is moving towards east and another body of equal mass is moving towards north. unit of magnetic flux is (a) tesla (b) oersted (c) weber (d) gauss.
