(a) Direction of electric field line is same as the direction of electric field
 
(b) Density of electric field lines indicates the intensity of electric field. If Fiel lines are very close then Intensity is greater .
If field lines are far apart  intensity is less .
 
(c) Electric field lines will not intersect
 
(d) Electric field lines will emerge out from positive charge
 
(e) Electric field lines will enter into negative charge

------------------------------------------------------------------------
Fig. (1) shows the electric field lines when q1 + q2 = 0 . Since sum of charges is zero , bothe charges have equal magnitude but oposite in sign.
Fig. (2) shows the electric field lines when q1 > 0 .  Charge is positive . Electric field lines are emerging out radially.
Fig. (3) shows the electric field lines when q1 q2 > 0 . bothe charges are positive.
Fig. (4) shows the electric field lines with  +4q  and  +2q charges .  +4q charge has more lines compare to +2q charge

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})
