A particle of mass 0.5 g and charge 2.5×10−8 C is moving with velocity 6×104m/s. What should be the minimum value of magnetic field acting on it, so that the particle is able to move in a straight line ? (take g = 9.8m/s2) |
0.327 Weber/m2
3.27 Weber/m2 32.7 Weber/m2 none of these |
3.27 Weber/m2 |
Use : mg = qvB B = 3.27 Weber/m2 |
