Question

an electric dipole consists of two opposite charges of magnitude 2×10^-6 each and separated by a distance of 3 cm.it is placed in an electric field of 2×10^-5 Nc^-1. determine the maximum torque on the dipole​

Answer 1

Given data,

Charges(q)=2×10−6C,

Distance(d)=3cm=3×10−2m 

electric field(E)=2×105N/C.

Torque(τ)=?

We know that 

Torque(τ) to be measured

Torque=charge×distance×Electric field

Torque(τ)=(2×10

Answer 2

$\Large\mathtt\green{ }\huge\underline\mathtt\red{Answer : }$

Given data,

Charges(q)=2×10−6C,

Distance(d)=3cm=3×10−2m 

electric field(E)=2×105N/C.

Torque(τ)=?

We know that 

Torque(τ) to be measured

Torque=charge×distance×Electric field

Torque(τ)=(2×10−6)×(3×10−2)×(2×105)

=12×10−3Nm
