Question

An electric dipole has a fixed dipole
moment p
→
, which makes angle θ with
respect to x-axis. When subjected to an
electric field
→ ∧
E E 1= i , it experiences a
torque
→ ∧
T1= τ k . When subjected to
another electric field
→ ∧
E 3 E 2 1 = j it
experiences a torque
→ →
T T 2 1 =− . The angle
θ is :
(1) 30°
(2) 45°
(3) 60°
(4) 90°

please answer fasttttttt

Answer 1

answer will be option 3..60°

Answer 2

Question:-

An electric dipole has a fixed dipole

moment p

→

, which makes angle θ with

respect to x-axis. When subjected to an

electric field

→ ∧

E E 1= i , it experiences a

torque

→ ∧

T1= τ k . When subjected to

another electric field

→ ∧

E 3 E 2 1 = j it

experiences a torque

→ →

T T 2 1 =− . The angle

θ is :

(1) 30°

(2) 45°

(3) 60°

(4) 90°

Explanation:-

T - T = (p.i + P3) × (Ei × 3Ej) <br> = px x V3Ek + p,BC - k) 0 = Ek(73pa – Py)

Py V3i. e. , tan 0 V3

Answer:-

0 = 60°
