The amplitude of (1+isqrt(3))/(sqrt(3)+i...

The amplitude of `(1+isqrt(3))/(sqrt(3)+i)` is a. `pi/3` b. `-pi/3` c. `pi/6` d. `-pi/6`

Text Solution

Verified by Experts

` Z= (1+sqrt3i)/(sqrt3 +i) `
` ((1+sqrt3i)/(sqrt3 + i)) * ((sqrt3-i)/(sqrt3-i)) `
` = (2sqrt3 +2i)/4 `
:. amplitude of Z is ` tan^-1(1/sqrt3) = pi/6 `
