How can a metallic sphere be charged negatively without touching it ?

An accelration produces a narrow beam of protons, each having an initial speed of v_(0) . The beam is directed towards an initially uncharges distant metal sphere of radius R and centered at point O. The initial path of the beam is parallel to the axis of the sphere at a distance of (R//2) from the axis, as indicated in the diagram. The protons in the beam that collide with the sphere will cause it to becomes charged. The subsequentpotential field at the accelerator due to the sphere can be neglected. The angular momentum of a particle is defined in a similar way to the moment of a force. It is defined as the moment of its linear momentum, linear replacing the force. We may assume the angular momentum of a proton about point O to be conserved. Assume the mass of the proton as m_(P) and the charge on it as e. Given that the potential of the sphere increases with time and eventually reaches a constant velue. The limiting electric potential of the sphere is

Which one of the following is not a unit of electric potential ?

Statement-1 : A conducting sphere charged upto 50V is placed at the centre of 100V and connected by a wire. All the charge of the shell flows to the sphere Statement-2: The positive charge always flows from higher to notential.

A solid conducting sphere having a charge Q is surrounded by an uncharged concentric conducting hollow spherical shell. Let the potential difference between the surface of the solid sphere and that of the outer surface of the hollow shell be V. If the shell is now given a charge of -3Q , the new potential difference between the same two surfaces is :

A conducting sphere of radius R is given a charge Q. The electric potential and the electric field at the centre of the sphere respectively are
