Define dipole moment of an electric dipole. Is it a scalar or a vector?

Electric dipole moment, p = 4 × 10−9 C m Angle made by p with a uniform electric field, θ = 30° Electric field, E = 5 × 104 N C−1 Torque acting...

Answer is (a) π  \(\vec{A}\times\vec{B}\) = AB sinθ \(\hat{n}\) \(\vec{B}\times\vec{A}\) = AB sin(2π - θ)\(\hat{n}\) AB sinθ \(\hat{n}\) = AB sin(2π - θ)\(\hat{n}\) θ = 2π - θ 2θ = 2π θ = π 

(a) : vector a = 8vector b vector c = - 7vector b vector a and vector b are parallel and vector b and vector c are antiparallel. Thus vector a and vector c are...

The correct answer is (c) α < β if A > B 

(b) It is possible to have | vector C | < | vector A | and | vector C | < | vector B | 

(c) A is correct but B is wrong

Thanks mam And big thanks to this app that solves most of the jee question

A +B=? How?

vector a || vector b ⇒ vector a × vector b = vector 0 ⇒ i(–9 – 3λ) + k(2λ + 6) = vector 0 ⇒ λ = – 3.

Time is an example of Scalar
