38. In the given diagram meters are not ideal. If reading of ammeter and voltmeter are 6A and 30V respectively then :- ww-A R (1) R=50 (2) R>50 (3) R <50 (4) All the above are possible 39. A cell of constant e.m.f. is first connected to a resistance R and then connected to a resistance R2. If power delivered in both cases is equal, then the internal resistance of the cell is (1) RR (2) (3) (4) R1 R2 - R1 R2 2 R1+ R2 2 40. Keeping the principal of conservation of linear momentum in mind, which diagram is not correct :- m (1) 0 m m (2) G m, m m 90 (3) m m (4) BQ m 90 m 0. m 41. A bomb explodes into two parts of masses 3 kg and 1 kg. If the total kinetic energy of the two parts is 6.0 104 joule then the momentum of the lighter part shall be (in kg m/s) :- (1) 2 10 (2) 3 103 (3) 2 10 (4) 3 102 38.
