Problem 2: A certain corner of the room is
selected as origin of the rectangular coordinate system. If an insect is
sitting on an adjacent wall at a point whose coordinates are (2, 1, 0) in units
of meter, what is the distance of the insect from this corner of the room?

Solution

Given Coordinates of the position= (2, 1, 0)

Required

Modulus
of the Position vector.

Let
â€˜Râ€™ be the position vector of the insect. Since its coordinates are (2, 1, 0),
therefore,

This
equation represents the distance of the insect from the corner of the wall.
