Question

(a) A car moving in a rectangular path

(b) A bicycle moving in a circular path

(c) A rocket moving into space

(d) A truck moving in an infinite spiral

The question was asked in quiz.

I want to ask this question from Motion in a Plane topic in portion Motion in a Plane of Physics – Class 11

Answer 1

Right choice is (c) A rocket moving into space

The best I can explain: A rocket moving into space is an example of 3-dimensional motion. Hence, it cannot be out in the category of motion in a plane. Rest all examples of motion in a plane. The truck moving in an infinite spiral is also an example of motion in a plane as spiral is a 2-dimensional entity.
