Answer 1

A dipole of dipole moment p is placed in a non uniform electric field along x axis. electric field is increasing at the rate of 1v/m then the force on dipole is...

answer : force on dipole = p

explanation : given, A dipole of dipole moment p is placed in a non-unifrom

electric field along x - axis. Let us consider that E(x) is electric field along x-axis.

now, electric field is increasing at the rate of 1 V/m . i.e., dE(x)/dx = 1V/m.

we know, force due to dipole is given by, F = dipole moment × electric field gradient

= p × dE(x)/dx

= p × 1

= p

hence, force on the dipole should be p

Answer 2
