A positive charge (very small sphere) q2=+5μC, m=1g is hung from silk thread of length 1m (as shown) between two big charged planes. Left plane is positively charged, right plane is negatively charged. If Θ =30, what is the magnitude of the electric field between the plates? What is the potential difference between these two planes? Show free-body diagram.

Two small insulating spheres with radius 6.00×10−2 mm are separated by a large center-to-center distance of 0.460 mm .

Consider the following apparatus for measuring the charge per mass (q/m) ratio of the proton. This apparatus employs the same physics as in mass spectrometers. It consists of a pair of plates that accelerate a beam of protons starting from rest at the left-most plate to a speed of 1 x 107 m/s, followed by a velocity selector set to only pass this speed, and a final set of deflector plates. (a) The left side of the accelerator plate is...

When we observe two charged balloons dangling from thin thread, they can repel each other. We tend to use small thin water balloons so they behave the right way. The balloons accumulated approximately equal amounts of charge. If we touch them together they can share charge and have equal charge. You are going to hang the two charged balloons from a rod/stick, on a string hung over the rod—making an inverted V like picture. The balloons will then repel. The...
