Question

Two point dipoles p^k and p2^k are located at (0,0,0) and (1m,0,2m). Find the field at the point (1,0,0).
  1. 9p32πε0^k
  2. 7p32πε0^k
  3. 7p32πε0^k
  4. none of these

A
none of these
B
7p32πε0^k
C
7p32πε0^k
D
9p32πε0^k
Solution
Verified by Toppr

The given point is on axis of ¯p2 dipole and at equatorial line of ¯p dipole so that field at given point is (¯E1+¯E2)
¯E1=2K(p/2)23=Kp8(+^k)
¯E2=Kp1(^k)
¯E1+¯E2=78Kp(^k)=7p32πε0^k
