Question

Transform the vector A = 3i – 2j – 4k at P(2,3,3) to cylindrical coordinates

(a) -3.6j – 4k

(b) -3.6j + 4k

(c) 3.6j – 4k

(d) 3.6j + 4k

I got this question in an online interview.

The above asked question is from Cartesian Coordinate System in section Coordinate Systems and Transforms of Electromagnetic Theory

Answer 1

Right answer is (a) -3.6j – 4k

To explain: Convert the Cartesian form to cylindrical form by formula and substitute the points to get -3.6j – 4k.
