How can we find the net electric field at a point due to a charge distribution?
Asked by Topperlearning User | 16 Apr, 2015, 09:50: AM
answered-by-expert Expert Answer

We can apply superposition principle to find the resultant electrostatic force at a point due to multiple charges.

Let’s consider a group of charges , , , …, etc with position vectors , , , …, etc  with respect to a given point  P.

,

Then according to the superposition principle net electric field at P due to the system of charges is the vector sum of the electric field due to each charge at P.

Hence,

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})
