1.) For the arrangement shown, if q, = +2e, q2 = -e, q3 = +e, T12 = 10 cm, and r23 5ст: a. What is the E field at the point in space occupied by particle 2? b. What is the force (and direction thereof) experienced by particle 2? 12 T23 93

A single proton is accelerated in a uniform E-field (directed eastward) at 3.2x10^8 m/s^2. Find the magnitude of the field and direction of the acceleration.

1. Calculate the solutions to the following question.Two tiny spheres of mass 7.80 mg carry charges of equal magnitude, 72.0 nC, but opposite sign. They are tied to the same ceiling hook by light strings of length 0.530 m. When a horizontal uniform electric field E that is directed to the left is turned on, the spheres hang at rest with the angle θ between the strings equal to 58.0∘.A) Which ball (the one on the right or the one on the left) has positive charge?B) What is the magnitude E of the field? (Don't forget to add units!)

2. (Ch. 20 Problem 60 in Wolfson) An electron is moving in a circular path around a long, uniformly charged wire carrying 1.4 nC/m. What's the electron's speed?
