If the direction ratios of a line are `1 + lambda, 1- lambda, 2,`
and it makes an angle of `60^(@)` with the y-axis then
`lambda` is

If the direction ratios of a line are 1+lambda, 2-lambda, 4 and if it makes an angle of 60^(@) with the y- axis, then the sum of the values of lambda is

If the direction ratios of two lines are (1, lambda, 2) and (lambda, lambda + 1, lambda) and the angle between the lines is 90^(@) then the modulus of sum of all values of lambda is ________

If a circle passes through the points of intersection of the lines 2x-y +1=0 and x+lambda y -3=0 with the axes of reference then the value of lambda is :

If a circle passes through the point of intersection of the lines x+ y +1=0 and x+ lambda y-3=0 with the coordinate axis, then find the value of lambda .

If the points A(lambda, 2lambda), B(3lambda,3lambda) and C(3,1) are collinear, then lambda=
