Two plane metal plates 4 cm long are held horizontal 3 cm apart in a vacuum one being vertically one above other. The upper plate is at a p. d 300 volt and the lowered is earthed. Electrons having velocity of 10^7 m/s are injected horizontally midway between the plate and in a direction parallel to the 4cm edge. Calculate the vertical deflection of the electron beam as it emerges from the plates. (e/m=1.8 x 10^11Ckg^- 1).

Estimate the kinetic energy of the neptune with respect to the sun as the sum of the terms, that due to its daily rotation about its axis, and that due to its yearly revolution about the sun. [assume the neptune is a uniform sphere with mass = 1.0×1026 kg , radius = 2.5×1010 m , rotation period 16.1 h , orbital period 6.01×104 d and is 4.6×109 km from the sun.]
