Question

Two charges +q and –q, each of magnitude 6.0 × 10–6 C, form a dipole. The separation between

the charges is 4 × 10–10 m. Calculate the dipole moment. If this dipole is placed in a uniform electric

field E = 3.0 × 102NC–1

at an angle 30° with the field, calculate the value of torque on the dipole.​

Answer 1

Answer:

12×10−3Nm

Explanation:

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
