Q3.f(z) = u(x,y) + iv(x,y) is an analytic function of complex variable z =
x + i y where 𝑖 = √−1. If u(x,y) = 2xy, then v(x,y) may be expressed
as
Answer : Option AExplaination / Solution:
Given that f(z) = u(x,y) + iν (x,y) is analytic function of complex
variable z = x + iy. Then the function derivatives can be given as,
Q4.Consider a Poisson distribution for the tossing of a biased coin. The
mean for this distribution is μ. The standard deviation for this
distribution is given by
Answer : Option AExplaination / Solution:
As we know that, for the poisson distribution,
Q5.Point mass M is released from rest and slides down a spherical bowl
(of radius R) from a height H as shown in the figure below. The
surface of the bowl is smooth (no friction). The velocity of the mass
at the bottom of the bowl is
Answer : Option CExplaination / Solution:
From the principle of energy conservation,
Kinetic energy at the bottom = Potential energy at height H
