[" The work done in moving a particle from a point "(1,1)" to "(2,3)" in a "],[" plane and in a force field with potential "u=lambda(x+y)" is "],[0-3 lambda],[0]

A particle is moving from a point (2m, 3m) to (1m, 1m) under the influence of force with potential energy U = lambda (x + y) . If work done by the force is n lambda , then find the value of n.

If the product of distances of the point (1,1,1) from the origin and plane x-y+z+lambda=0 be 5 then lambda=

If the product of distances of the point (1,1,1) from the origin and plane x-y+z+lambda=0 be 5 then lambda=

Calculate the work done by the force vec(F)=yhati to move the particle from (0, 0) to (1, 1) in the following condition (a) y = x (b) y=x^(2)

Calculate the work done by the force vec(F) = y hat(i) to move the particle from (0,0) to (1,1) in the following condition (a) y = x (b) y = x^(2)

If the tangents from the point (lambda, 3) to the ellipse x^2/9+y^2/4=1 are at right angles then lambda is

If the tangents from the point (lambda, 3) to the ellipse x^2/9+y^2/4=1 are at right angles then lambda is

If the tangents from the point (lambda, 3) to the ellipse x^2/9+y^2/4=1 are at right angles then lambda is
