Three charges q1, q2 and q3 of different magnitudes are aranged as shown in figure. Calculate the net force on the charge qz? 93 =+ 1.8 x 105c 3.00 m 92 = - 1.2 x 105c 3.00 m 91 = +4.5 x 105c Two golf balls have equal and opposite electric charges on them. Ball A has a charge 12µC and ball B has a charge of -12µC. They are brought in touch with each other, so that both of them become electrically neutral. Calculate the number of electrons involved in the process?
