Calculate the magnitude of strength of an electric field at the distance of 12.0 nm from the nucleus of the Uranium-235 atom?

A point charge q1 = +5.00 μCoul is held in fixed space. From a horizontal distance of 6.00 cm, a small sphere with mass 4.00*10^-3 kg and charge q2 = +2.00 μCoul is fired toward the fixed charge with an initial speed of 50.0 m/s. Gravity can be neglected. What is the distance between the two charges when the speed of the moving charge q2 is 20.0 m/s?

A mobile –5.40 mC charge (m = 230.0 g) is placed 45.0 cm from a –15.1 mCstationary charge that is generating an electric field. If the -5.40 mC charge starts from restand starts moving away from the stationary charge how fast will it be traveling when itreaches 240.0 cm away?

An electron and a proton are fixed at a separation distance of 917 nm. Find the magnitude and the direction of the electric field at their midpoint. E = N/C The direction is perpendicular to the line of the particles. O is toward the proton. is toward the electron. cannot be determined.

Two small balls with a mass of 2 g each are hanging on two separate strings 0.5  m (50 cm)  long attached to a common point. They are given an identical negative charge and spread apart to a distance 6 cm from each other. How many excess electrons are there on each ball not cancelled by positive charge?
