ocr: 2. a) Find the equation of the line of intersection between 1 the two planes: x+2y+32=4 and 3x+2y+2 = T b) How far is the point (1,1,1) from the line in part (a)? c) How far is the point (1,1,1) From the first plane in part (a)? 3. A force field F is given by 2 sinz, x2y cosz-e*). f= (-ze*+2xy sinz, X a) Is this field conservative? Give reasons. b) Set up an integral giving the amount of work done in going from (0,0,0) to (1,1,1) along the path f-t ti+t25+t38. c) What is the curvature of the path at t=1?
