Answer 2

Answer:

The correct answer to this question is  |P| = |Q|

Explanation:

Given - Two vectors of magnitudes p and q are of magnitude' q's . if the magnitude of q is doubled now the angle made by the new resultant with p.

To Find - Write the new resultant with p.

A vector is a two-dimensional entity with both magnitude and direction. A vector can be seen geometrically as a directed line segment with an arrow denoting the direction and a length equal to the magnitude of the vector. The vector's direction is from the tail to the head.

Now, take AB as the vector P, and BC as the vector Q

Then, the resultant is the CA vector.

When Q is doubled and the resultant is DA vector, and it makes the angle which is 90° with P vector and

we assumed |P| = |Q|
