TIFR ECE 2023 | Question: 12
Consider a disk $D$ of radius $1$ centered at the origin. Let $X$ be a point uniformly distributed on $D$ and let the distance of $X$ from the origin be $R$. Let $A$ be the (random) area of the disk with radius $R$ centered at the origin. Then $\mathbb{E}[A]$ is $\frac{\pi}{3}$ $\frac{\pi}{6}$ $\frac{\pi}{4}$ $\frac{\pi}{2}$ None of the above

GATE ECE 1991 | Question 6
In figure, the operational amplifier is ideal and its output can swing between $-15$ and $+15$ volts. The input $v_\rho$ which is zero for $t<0$, is switched to $5$ volts at the instant $\mathrm{t}=0$. Given that the output $v_0$ is ... $v_0$ and $v_i$. You must give the values of important parameters of this sketch.

GATE ECE 1991 | Question 1.11
The characteristic equation of a feedback control system is given by $ s^3+5 s^2+(K+6) s+K=0 $ Where $K>0$ is a scalar variable parameter. In the root loci diagram of the system the asymptotes of the root locus for large values of $\mathrm{K}$ meet at a point in the $s$-plane whose coordinates are $(-3,0)$ $(-2,0)$ $(-1,0)$ $(2,0)$
