why electric field lines donot form any closed loops and explain the physical significance of electric field

  • Electric field lines from a single polarity can never form a closed loop.
  • As the propagation of these field lines is guided by the inverse square law. i.e 1 over straight r squared
  • The propagation is inversely proportional to the square of the distance of the field lines.
  • Therefore, the electric field lines are propagated always radially inwards or radially outwards.
  • This is the reason why they don't form a closed loop.
  • However, it should be noted that the electric field lines of both the poles do form a closed loop.

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})
