The equation of straight line shown in figure is :

Options

A. `V_(0)//2`
B. `V_(0) // sqrt(3)`
C. `V_(0)`
D. `V_(0)//sqrt(2)`

Answer

D

Explanation

`{{:(V_(0)","0 lt t lt T// 2),(0", " T // 2 lt t lt T):}`
`V_(rms) = sqrt((1)/(T) [ int_(0)^(T//2)V_(0)^(2) dt + int _(T//2)^(T) (0)^(2) dt])`
`= sqrt((1)/(T) xx V_(0) ^(2) xx (T)/(2)) = (V_(0))/(sqrt(2))`
