Two positively charged spheres are shown in the figure below. Sphere 1 has twice as much charge as sphere 2; q = 5.55 nC, d = 0.350 m, and y = 1.15 m. Suppose an electron is placed at point A and released. (Express your answers in vector form.) 91 = 2q 92=9 d/2d/2- (a) What is the electron's acceleration? ae = m/s² (b) If the electron were replaced by a proton, what is the proton's acceleration? ap m/s²

The electron and proton of a hydrogen atom are separated by a distance of approximately 5.3*10-11 m. Charge of electron (de)= -1.61*10-19 C, charge of proton (qp)= 1.61*10-19 C, electric constant (K₂)= 8.988*109 N.m²/C2. Find the electric force exerted by the proton on electron. Submit your answer in exponential form with four decimal places.

In the ever popular game from the future, Electrodisc, players can score double points by pushing a disc into another disc with the electric field generated by a third disc. The discs are by regulation 1 kg. All discs have the same shape and are made of the same conducting material. In the figure below, disc 1 is held in place, and disc 2 is held stationary 4.1 m from disc 1 by a player. The player then releases disc 2. 10 m. F12 What is the initial magnitude of the acceleration imposed on the second disc? The charge on the first disc is 1.7 mC. The charge on the second disc is 1.7 mC. The charge on the third disc is neutral. m/s² Later, discs 2 and 3 touch and charge is exchanged. How much charge is exchanged once the charges on each disc reach an equilibrium? mC After charge is exchanged, what is the direction of the force on disc 3 due to disc 2? O toward the left O toward the right O upward O downward

Given the arrangement of charged particles in the figure below, find the net electrostatic force on the 9₁ = 5.15-μC charged particle. (Assume q2 = 16.33 µC and 93 = -19.12 μC. Express your answer in vector form.) 7 = X N 91 (-2.00 cm, 0) 93 (1.00 cm, 1.00 cm) 92 (0, -1.00 cm)
