A vector A points vertically upward and B points towards north. The vector product A x B is

(d) upward In accordance with Fleming's left-hand rule, the direction of magnetic field is vertically upward.

Since the positively charged particle (alpha-particle) projected towards west, so the direction of current is towards west. Now the deflection is towards north, so the force is towards north' Now...

The correct answer is (c) vA = vB  Explanation: The ball 'A' thrown vertically upward will return back to the initial point with the same thrown speed but its direction will be downwards....

(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...

(d) downward.

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 | 

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.
