Two particles are in a uniform electric field whose value is +2500 N/C. The mass and charge of particle 1 are m₁ = 1.61 × 10-5 kg and 91=-5.61 C, while the corresponding values for particle 2 are m2 = 2.14 × 105 kg and q2=+16.5 μC. Initially the particles are at rest. The particles are both located on the same electric field line but are separated from each other by a distance d. When released, they accelerate, but always remain at this same distance from each other. Find d. Number Units

A 3.35×10−5 kg3.35×10−5 kg positively charged ball with charge ?=7.75×10−6 Cq=7.75×10−6 C is resting on a flat, frictionless horizontal surface. For a time of ?=0.255 s,t=0.255 s, a constant electric field of magnitude ?=635 N/CE=635 N/C is directed vertically to the ball, which makes the ball rise to a height of ?.d. After this time, the electric field is turned off and the ball returns to the surface. Calculate, in meters, how high the ball is lifted off of the surface during the time ?.

One end of a light spring with force constant k = 125 N/m is attached to a wall, and the other end to a metal block with charge A 1.94 μC on a horizontal, frictionless table as shown in the figure. A second block with charge qB -3.52 μC is brought close to the first block. The spring stretches as the blocks attract each other so that at equilibrium, the blocks are separated by a distance d = 12.8 cm. What is the displacement x of the spring?
