Ex. Find the vector whose magnitude is 15 and which is perpendicular to ( k) and lies in the plane pm 2x3y z = 15. Then the gradient of d is perpendicular to the surface = constant. L.e. is perpendicular to the required vector which is also perpendicular to the vector (i+K). Thus we have a vector along the required vector such that Sol. Let 2x 3y+Z 15 constant. grad-V(2x+3y+2)=2i+3]+k A- )xgrad - kx(2i 3 k)

    my approach is the required vector is perpendicular to j+k vector so the dot product of required vector(V) and j+k is zero. and also the V vector is on the plane 2x+3y+z so the gra...

    A vector is not a required vector,it is just a vector along our required vector..
  • Vaishnavi rajora thankyou
    dear must remember that gradiant is perpendicular to the surface.

    and if we want perpenducular to that we need cross product
