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 S_{C} 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 (r^{n+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,set2]
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 Set2]
