a) The figure shows an arrangement of two -1.9 nC charges, each separated by 5.0 mm from a proton. If the two negative charges are held fixed at their locations and the proton is given an initial velocity v as shown in the figure, what is the minimum initial speed v ( in km/s) that the proton needs to totally escape from the negative charges? (k = 1/4πε0 = 8.99 × 109 N.m2/C2, e = 1.60 × 10-19 C, mproton = 1.67 x 10-27 kg)

b) Particle A (mass = m, charge = Q) and B (mass = m, charge = 5 Q) are released from rest with the distance between them equal to 1.0 m. If Q = 17.5 μC, what is the kinetic energy (in J) of particle B at the instant when the particles are 3.0 m apart?

An alpha particle is a nucleus of helium. It has twice the charge and four times the mass of the proton. When they were very far away from each other, but headed toward directly each other, a proton and an alpha particle each had an initial speed of 0.002c, where c is the speed of light. What is their distance of closest approach? Hint: There are two conserved quantities. Make use of both of them. (c = 3.00 × 108...

Two positive charges, each with a charge of ?=55.0 μC, Q=55.0 μC, are held fixed at a distance ?=21.00 cm L=21.00 cm to either side of a particle of charge ?=−4.50 μC q=−4.50 μC and mass ?=4.50 g. m=4.50 g. This particle is constrained to move along a vertical frictionless wire halfway between the two charges, as indicated in the figure. Neglecting any gravitational effects, determine the frequency ? f of small‑amplitude oscillations of the particle.
