2 Which of the following particle would experience the largest magnetic force when projected with the same velocity perpendicular to a magnetic field? Proton Electron He<sup>+</sup> Li<sup>+</sup>
3 Shunt required in an ammeter of resistance R to decrease its deflection from 30 ampere to 10 ampere is R/4 R/3 R/2 R
4 The magnetic moment of a circular coil carrying current is Directly proportional to the length of the wire in the coil Inversely proportional to the length of the wire in the coil Directly proportional to the square of the length of the wire in the coil Inversely proportional to the square of the length of the wire in the coil
5 Choose the correct statement Both an ammeter and voltmeter should have small resistance Both an ammeter and a voltmeter should have large resistance An ammeter should have large resistance and a voltmeter should have small resistance An ammeter should have small resistance and a voltmeter should have large resistance
6 A moving charge will gain energy due to the application of Electric field Magnetic Both of these None of these
