the distancde betwen a parallel plate capictor is 5d the positively charged plate is at x=0 and the negatively charged plate is at x=5d. Two slabs of equal thickness d is inserted bet ween them. One is conductor and another is dielectric. the conductor is placed at d and the dielectric is inserted at 3d. Plot the graph of potiential versusdistance graph

The potential versus distance graph will be as shown below:
 
 
The potential decreases gradually from x = 0 to x = d.
As it encouters a conductor, the potential remains constant throughout the distance. Hence, it remains same from x = d to x = 2d.
 
Then it decreases again with the same rate as before till x = 3d.
 
Then, it encounters a dielectric because of which the rate of drop changes.
 
After this the drop is same as before till x = 5d, i.e., till the negative plate.

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})
