K.C.S.E Physics Q & A - MODEL 1997PP2QN05
(b) In the set up in figure 5, the suspended metre rule is in equilibrium balanced by the magnet and the weight shown. The iron core is fixed to the bench
(i) State and explain the effect on metre rule when the switch S is closed
(ii) What would be the effect of reversing the battery terminals
(iii) Suggest how the set up in figure 5 can be adapted to measure the current flowing in the current circuit.
(c) Electrons emitted from a metal when light of a certain frequency is shone on the metal are found to have a maximum energy of 8.0 x 10-19J. If the work function of the metal is 3.2 x 10-19J, determine the wavelength of the light used
