Three identical dipoles are arranged as shown below. What will be the net electric field at `P`? `(k=1/(4pi epsilon_(0)))`

A

`(K.p)/(x^3)`

B

`(2Kp)/(x^3)`

C

Zero

D

`(sqrt2Kp)/(x^3)`

Text Solution

Verified by Experts

The correct Answer is:
C
`E_1=(Kp)/x^3(-hati)`
`E_2=(Kp)/(x^3)(-hati)`
`E_3=(2Kp)/(x^3)(hati)`
`E_1+E_2+E_3=0`

If the elctron ( charge of each electron =-e) are shifted by a small distance x,a net + ve charge density ( per unit area ) is induced on the surface. This will result in an electric field E=n ex //epsilon_(0) in the direction of x and a restoring force on an electron of -(n e^(2)x)/(epsilon_(0)) , Thus m ddot(x) =-(n e^(2)x)/(epsilon_(0)) or ddot(x) + ( n e^(2))/( m epsilon_(0))x=0 This gives omega_(p)= sqrt((n e^(2))/( m epsilon_(0)))=1.645xx10^(16)s^(-1) as the plasma frequency for the problem,.
