Lesson 4.1 Homework 1. Find the magnetic force on a proton moving with a velocity of 4.46 Mms -1 i in a magnetic field of 1.75 T k 2. A uniform magnetic field of magnitude 1.48 T is in the positive z-direction. Find the force exerted by this field on a proton if its velocity is (i) v = 2.7 Mms -1 i , (ii) v = 3.7 Mms -1 j , (iii) v = 6.8 Mms -1 k and (iv) v = 4.0 Mms -1 i + 3.0 Mms -1 j 3. A straight wire segment 2.0 m long makes an angle of 30 o with a uniform magnetic field of 0.37 T. Find the magnitude of the force on the wire if it carries a current of 2.6 A. 4. What is the force on an electron with a velocity v = (2 i – 3 j ) Mms -1 in a magnetic field B = (0.8 i + 0.6 j – 0.4 k ) T 5. A straight, stiff horizontal wire of length 25 cm and mass 50 g is connected to a source of emf by light flexible leads. A magnetic field of 1.33 T is horizontal and perpendicular to the wire. What should be the current in this wire so that the magnetic force on it will balance its weight. 6.
