Hi,

l am asking ..perhaps a stupid question ...nevertheless its important I get this right.

Plz check methodology .

Thanks.

F=xyi-(2z^2)j+yzKCalcuate the work done by F along the straight line joining the points (1,0,0) and (2,2,3)

This is what I did: set the parametric eqn using given points

then gather x,,y,z in terms of t

dr can be expressed in terms of t

I used the followign parametric eqns :

x=1+t

y=2t

z=3t

anyhow,everything has to be in terms of t otherwise it cant be integrated.

I integrated t :0 to 1

finally I get something like -33 which is very wrong.
