A parametric description of the sphere for u € [0, ], ve[0,21] is given by r(u,v)=(asin ucosv, a sinusinv, acosu). Then a normal vector is Select one O A. n= aʼsinucosv,a- sin’usin v, a’sin vcosu n= a sin’ucosv,a sin’usin v, a sin u cosu) n=(a’ sin’ucos’v,aʼsin’usin’v, a’ sin ucosu) n= (a’sin’ucosv,a’ sin’usinv, a’ sinucosu OB. OC OD

Let o be a scalar potential function of a conservative field F. Then the work done in a moving particle along a curve C from point A to B is (A) (A) - 0(B) (B) O (C) °(B) + (A) (D) (B) - (A)

x2 The area of the ellipse ****=1 is ...... 9 16 Select one: O AT O B. 12 ос. Зл O D. 41

The curl of a vector function F = æ?î + 2zÀ – yť is a = (A) -3 (B) -3 (C) (D) -3
