EduRev is a knowledge-sharing community that depends on everyone being able to pitch in when they know something. a) 0 b) Solenoidal A vector field with a vanishing curl is called as __________ The curl of vector field $$\vec{f} (x,y,z) = x^2\hat{i} + 2z \hat{j} – y \hat{k}$$ is _________ This means sketch it if you can, and you should probably compute … students definitely take this Vector Calculus - 1 exercise for a better result in the exam. 1. d) Irrotational field Also we note that z coordinate of each vertex of the triangle is zero. The region R is bounded by two closed circles C1 and C2, so it is doubly connected. The most important object in our course is the vector field, which assigns a vector to every point in some subset of space.. We'll cover the essential calculus of such vector functions, and explore how to use them to solve problems in partial differential equations, wave mechanics, electricity and magnetism, and much more!. a) $$-3\hat{i}$$ View Answer, 2. This test is Rated positive by 87% students preparing for Mathematics.This MCQ test is related to … So, line integral of the vector from point (0, 0, 0) to (1, 1, 1) is, If  are to arbitrary vectors with magnitudes a and b respectively,  will be equal to. (i + 3t2j)dt, The value of  by Stoke’s theorem, where   and C is the boundary of the triangle with vertices at ( 0 ,0 , 0 ) , ( 1 , 0 , 0 ) and ( 1 ,1 , 0 ) is, We have, curl  We take, b) Rotational field This set of Vector Calculus Multiple Choice Questions & Answers (MCQs) focuses on “Divergence and Curl of a Vector Field”. For it, we apply cut AD and consider the region R having simple closed curve ABCADEFDA in the anticlockwise direction. Now, for divergence Lines; 2.
