There are two identical, positively charged conducting spheres fixed in space. The spheres are 45.0 cm apart (center to center) and repel each other with an electrostatic force of F1 = 0.0720 N. Then, a thin conducting wire connects the spheres, redistributing the charge on each sphere. When the wire is removed the spheres still repel but with a force of F2 = 0.100 N. Using this information, find the initial charge on each sphere, q1 and q2 if initially q1 is less than q2.
find magnitude of the tension in the wire and magnitudes.
In uniform circular motion, a particle undergoes motion in a circular path with a constant speed. Which of the following statement is false and why?
A proton is projected perpendicularly into a magnetic field that has a magnitude of 0.30 T. The field is then adjusted so that an electron will follow a circular path of the similar radius when it is projected perpendicularly into the field with t..
