Q3
A particle having negative charge equal to that of an electron and mass 1.6×1030kg is projected with an initial speed u at an angle 45o to the horizontal from the lower plate of a parallel plate arrangement as shown in figure. The plates are sufficiently long and have a separation of cm. Then the maximum value of the velocity of the particle with which it can be projected so that it does not hit the upper plate is :(Take the electric field between the plates as 103Vm1 directed upward and gravity is ignored)

A particle of mass 9×1031kg having a negative charge of 1.6×1019C is projected horizontally with a velocity of 106ms1 into a region between two infinite horizontal parallel plates of metal. The distance between the plates is d=03cm, and the particle enters 0.1 cm below the top plate. The top and bottom plates are connected, respectively, to the positive and negative terminals of a 30 V battery. Find the components of the velocity of the particle just before it hits one of the plates
