In a transistor, `alpha` is related to `beta` by the relation

A

`beta = (1 - alpha)/(alpha)`

B

`beta = (alpha)/(1 - alpha)`

C

`alpha = (beta - 1)/(beta)`

D

`alpha beta = 1`

Text Solution

Verified by Experts

The correct Answer is:
B
From one side, `(t - x)/(5) = 1.5`
From other side, `(x)/(2) = 1.5 to x = 3`
`:. (t - 3)/(5) = 1.5 implies t = 7.5 + 3 = 10.05 cm`
