Ifis the angle between any two vectors ` -> a`and ` -> b`,then `| -> adot -> b|=| -> axx -> b|`when `theta`isequal to(a) 0 (B)`pi/4`(C) `pi/2`(d) `pi` |
|
Answer» Correct Answer - b Given that, `|vec(a).vec(b)|=|vec(a)xx vec(b)|` `implies |vec(a)||vec(b)| cos theta = |vec(a)||vec(b)|sintheta` `implies cos theta = sin theta` `implies tan theta = 1 implies theta = (pi)/(4)` |
