Reference no: EM13660775

A particle with a charge of -60.0 nC is placed at the center of anon conducting spherical shell of inner radius 20.0 cm and outer radius 27.0 cm. The spherical shell carries charge by a uniform density of -2.95 µC/m3. A proton moves in acicular orbit now outside the spherical shell. Compute the speed of the proton.
