Question

Scalar product of radius vector and tangential
velocity is
(a) zero
(b) rvsino
(c) rvcoso
(d) rv​

Answer 1

The answer of the question is (a) zero.....

Answer 2

Answer:

The correct option is a) zero

Explanation:

• An algebraic operation known as the scalar product or dot product takes two sequences of integers of equal length and produces a single number.
• The angle between the radius vector and tangential velocity is 90°
• The radius vector is perpendicular to the tangential velocity
• The scalar product is r.v = rv cos θ
• θ is the angle between the radius vector and tangential velocity
• θ = 90°
• cos 90° = 0
• The scalar product r.v = rv cos 90° = rv(0) = 0
• The scalar product does not have direction, it only has magnitude.

The scalar product of the radius vector and the tangential velocity is zero.
