Question

04. For the resultant of the two vectors to be maximum,
what must be the angle between them
(a) 0°
(b) 60°
(c) 90°
(d) 180°​

Answer 1

Answer:

0°

Explanation:

P+Q= root of(P^2+Q^2+2PQcostheta)

where theta is angle between vectors

so it will be max for costheta=1

theta=0°

Answer 2

Question:–

For the resultant of the two vectors to be maximum,

what must be the angle between them

(a) 0°

(b) 60°

(c) 90°

(d) 180°

AnswEr:—

$\longrightarrow$(a) 0° is the angle between the two vectors to give maximum resultant.

ExplainaTion:—

The resultant of a given vector id given by

→ |R|= √P²+Q²+PQcos∅

where,

•|R |= magnitude of resultant.

•P=|P|= magnitude of vector P.

•Q=|Q|= magnitude of vector Q.

•∅= angle between vectors P and Q.

The resultant the vector would be maximum when ∅ the angle between them is 0°.

It means the two vectors should be parallel to each other.
