Q. [1994 1M]
Ans:-
Exp- Using Stoke’s theorem
Q. If a vector field is related to another vector field
through
,Which of the following is true? Note: C and SC refer to any closed counter and any surface whose boundary is C. [2009 2M]
a)
b)
c)
d)
Ans-(b)
Exp- Stoke’s theorem
Q. Consider a closed surface S surrounding a volume V. If is the position vector of a point inside s, with
the unit normal on S,the value of the integral
[2011 1M]
a) 3 V
b) 5 V
c) 10 V
d) 15 V
Ans-(d)
Exp- For close surface, we can use Divergence Theorem.
Q. The direction of vector A is radially outward from the origin,with where
and K is a constant. The value of n for which
is [2012 2M]
a) -2
b) 2
c) 1
d) 0
Ans- (a)
Exp-
For to be zero, derivative must be zero in other words (rn+2) must be constant.
This could be possible only if n = -2.
Q. A vector is given by
Which of the following statements is True? [2015 1M,set-2]
a) is solenoidal,but not irrotational
b) is irrotational,but not solensoidal
c) is neither solenoidal nor irrotational
d) is both solenoidal and irrotational
Ans-(a)
Exp-
For solenoidal,
is solenoidal
For irrotational,
Q. If the vector function
is irrotational,then the values of the constants respectively,are[2017 2M Set-2]
a)
b)
c)
d)
Ans-(b)
Exp-
