Question

Consider the following statements about electric dipole and select the correct ones (multiple ones are correct)
SI : Electric dipole moment vector p is directed from the negative charge to the positive charge
S2: The electric field of a dipole at a point with position vector r depends on mod of vector r as well as the angle
between vector r and P
S3 : The electric dipole potential falls off as
$\frac{1}{ {r}^{2} }$
and not as
$\frac{1}{r}$
S4: In a uniform electric field, the electric dipole experiences no net force but a torque
t = P×E​

Answer 1

Answer:S1,S4,S3,S2(not sure for S2)

Explanation:S2:to find electric field at any point , equation is kp√(3cos^2theta+1)/r^3 ; where k is const.,p is the dipole moment.

S1 is the property of the dipole.

S4 is given in the NCERT class 12 electrostatic chapter.

S3 is correct because electric field is inversely proportional to r square.
