Electric field E at distance r from infinite line charge that has linera charge density λ is given as
 
begin mathsize 14px style E space equals space fraction numerator lambda over denominator 2 pi space r space epsilon subscript o end fraction end style
begin mathsize 14px style lambda space equals space left parenthesis space 2 space pi space r space epsilon subscript o space right parenthesis space E end style
λ = ( 2 π ) × 2 × 10-2 × 8.854 × 10-12 × 9 × 109 =  1 C/m

ln a Millikan’s oil drop experiment, the horizontal plates are 1.5 cm apart. With the electric field switch off an oil drop is observed to fall with a steady velocity of 2.5×10^{-2}  cm  s^{-1}.  When the field is switched on the upper plate being positive, the drop just remains stationary when the   p.d.   between the plates is 1500 V. Calculate the radius of drop (b) How many electronic charges does it carry? (c)If the   p.d. between the two plates remains unchanged, with what velocity will the drop move when it has collected two more as a result of exposure to ionising radiation? (Oil density, rho=900 kgm^{3} , Viscosity of air,   eta =1.8×10^{-5} Nsm^{-2}, Density of air,  σ=1.293  kg  m^{-3})
