Question

A vector is represented i + 2j + 3k, it's length in X Y plane​

Answer 1

Answer:

This is a pretty straightforward question. The length of a vector is nothing but it’s magnitude.

The given vector has components of 3, 1, respectively in the x and y directions. To determine its length we require it’s projection in the x-y plane. For this the x and y components should be sufficient.

It’s magnitude or length in a given plane is determined by:

x2+y2−−−−−−√x2+y2

where x and y denote the x and y components respectively.

Plugging in the values, the output obtained is:

32+12−−−−−−√32+12

which is:
