For component of a vector `A=(3hati+4hatj-5hatk)`, match the following table

Text Solution

Verified by Experts

The correct Answer is:
`ararrq;brarr r;crarrs; drarrs`
`vecA=3hati+4hatj-5hatk`
along vector `(2hati+hatj+2hatk)` we have to take projection.

`vecA.vecB=AB cos theta`
`A cos theta=((vecA.vecB)/(B))`
Along y-axis the component is 4 units.
