Acharge of -8.1 µc is traveling at a speed of 7.2 106 m/s in a region of space where there is a magnetic field. the angle between the velocity of the charge and the field is 50°. a force of magnitude 4.6 10-3 n acts on the charge. what is the magnitude of the magnetic field?

Explanation:

As we know that magnetic force on a moving charge is given by the formula

so we will have

now we will have

now we have

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m
