The sphere at `P` is given a downward velocity `v_(0)` and swings in a vertical plane. Othere end of the rope of `l=1m` is attached to a support at `O`. The rope breaks at angle `30^(@)` from horizontal, knowing that it can withstand a maximum tension equal to three times the weight of the sphere. Then the value of `v_(0)` will be: `(g=pi^(2)m//s^(2))`

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. One the potential of the sphere has reached its final, constant value, the minimum speed v of a proton along its trajectory path is given by
