A beam of unknown charged particles passes at right angle to the direction of magnetic field of 9.0 10-2 T. If the speed of the particles is 3.0 104 m/s and force experienced by a particle is 8.64 10-16 N, how many electric charges are carried by one particle? {Force} = F = {...

I want to understand this concept more than anything so advice as well as hints to solve this problem are greatly appreciated. 26. Two fixed charges, -4.0E-6 C and -5.0E-6 C, are separated by a certain distance. a) is the net electric field at a location halfway between the ...

A point charge (m = 1.0 g) at the end of an insulating string of length L = 51 cm (Fig. 16-66) is observed to be in equilibrium in a uniform horizontal electric field of E = 9200 N/C, when the pendulum's position is as shown in Fig. 16-66, with the charge d = 2.0 cm above the ...
