O magnetic m field? lctrons travels in a straght ine n a cetan egion Can we say tare o fiel Fq (vx B), which pairs are always perpendicular to each other. fiel 4 A charge q -4 uC has an instantaneous velocity v-( vard the east What s the sign of the charge on tie eard m magnetic field A particle initially moving towards south in a vertically downward magnetic field is deflecited B-(2i 5i-3 k)x 10 T. What is the force on the charge? 3)+ kx 10 m/s in a unitorm 6. An electron experiences a magnetic force of magitude 4.60 x 15 N, when moving at an angle of 60 with respect to a magnetic field of magnitude 3.50 x 10-3 T. Find the speed of the electron. 7. He 2 ion travels at right angles to a magnetic field of 0.80 T with a velocity of 10 m/s. Find the magnitude of the magnetic force on the ion.
Dear student,
Disclaimer:- the text of the question posted is not meaningful .However we are giving the solution considering question given in image format.
magnetic Force = qv x B
as angle between v and B is a right angle so sin900 = 1 . so , qv x B reduces to qvB
so magnetic force on above helium ion is = 2 x 1.6 x 10-19 x 105 x 0.8 = 2.56 x 10-14
Regards
