17 a An electron is shot directly toward the centre of a large metal plate that has surface charge density 2 0 x 10 6 Cm 2 The initial kinetic energy of the electron is 1 60 x 10 7 J The electron stops just when it reaches the plate due to electrostatic repulsion from the plate Calculate the distance of the starting point of the electron from the plate 3 b A 5 0 cm slab of ice is formed on an outdoor tank of water The air is at 10 C Find the rate of ice formation in centimeters per hour The ice has thermal conductivity 0 0040 cal s cm C and density 0 92g cm Assume there is no energy transfer through the walls or bottom 3
