The angle between rectangular components of vector is:

Explanation

(a) 45°: This option represents an angle of 45 degrees between the rectangular components of a vector. It means that the x-component and y-component of the vector would form a slanted line at a 45-degree angle. (b) 60°: This option represents an angle of 60 degrees between the rectangular components of a vector. It means that the x-component and y-component of the vector would form a slanted line at a 60-degree angle. (c) 90°: This option represents an angle of 90 degrees between the rectangular components of a vector. It means that the x-component and y-component of the vector would form a right angle, perpendicular to each other. (d) 180°: This option represents an angle of 180 degrees between the rectangular components of a vector. It means that the x-component and y-component of the vector would form a straight line, pointing in opposite directions. In the context of the question, the correct answer is (c) 90°, as it represents the perpendicular angle between the rectangular components of a vector.
