The following text gives a qualitative idea about Rutherford's alpha- particle scattering experiment. Applying some trigonometry and calculus, Rutherford got the following equation: cot ((0)/(2)) = (Kxx(KE))/(Ze^(2))xxb "where", K= "constant" =((1)/(9xx10))(c^(2))/(N-m^(2)) KE = initial kinetic energy of alpha- particle, e=1.6xx10^(-19)C In an experment with gold nucleus (assume Z=80) with impact parameter equal to 10^(-4)m the scattering angle was found to be 90^(@), What should be the initial KE of alpha- particle?

Two ships are there in the sea on either side of a light house in such a way that the ships and the light house are in the same straight line. The angles of depression of two ships are observed from the top of the light house are 60o and 45o respectively. If the height of the light house is 200 m, find the distance between the two ships. (U s e sqrt(3)=1. 73)
