Positive charge is placed on two conducting spheres that are very far apart and connected by a long, very thin conducting wire. The radius of the smaller sphere is 5.60 cm and the radius of the larger sphere is 10.5 cm. The electric field strength at the surface of the larger sphere is 215 kV/m. Find the surface charge density on the 5.60-cm sphere. (in C/m^2)

The law of reflection states that the angle of reflection is equal to the angle of

Juliette sets the initial velocity to +10 m/s, the acceleration to zero, and clicks “start.” how can shakina describe the subsequent motion of the car juliette controls?

An electron moves with a constant horizontal velocity of 3.0 × 106 m/s and no initial vertical velocity as it enters a deflector inside a tv tube. the electron strikes the screen after traveling 26 cm horizontally and 19 cm vertically upward with no horizontal acceleration. what is the constant vertical acceleration provided by the deflector? (the effects of gravity can be ignored.)
