Physics

Answer the following four sub-questions. Each sub-question isindependent and has no no link with the other sub questions. a) Twoneutral spheres are spaced 3 m apart. Calculate how many electronsmust be transferred from one sphere to another so that they eachexperience a force of 14 N, and say whether the forces will beattractive or repulsive. b) Calculate the uniform electric field tobe applied parallel to a moving proton at 2⋅106 m / s in order toimmobilize it in 20 µs, and say if this field must be oriented inthe direction of speed or in opposite direction. c) A longinsulating cylinder has a charge density of -1 µC / m3 . Thematerial component the cylinder suddenly becomes conductive; we seethat the density load area is then -1 µC / m2 . Calculate theradius of the cylinder. d) Calculate the magnitude of the electricfield at position r = 10 cm in question 4. Your gait must show,among other things, that the load (or surface density) of the shellthin has no effect on your response.
