In the given figure the angle (in degree) between the velocity vector of object and image is `alpha` . The value of `(alpha)/(10)` is

Relation Between Velocity Of Object And Image

The angle between the lines with direction ratios (1,0,pmcosalpha)" is "60^@ . What is the value of alpha ?

For some non zero vector vecv , if the sum of vecv and the vector obtained from vecv by rotating it by an angle 2alpha equals to the vector obtained from vecv by rotating it by alpha then the value of alpha , is

For some non zero vector vecv , if the sum of vecv and the vector obtained from vecv by rotating it by an angle 2alpha equals to the vector obtained from vecv by rotating it by alpha then the value of alpha , is

A point moves according to the law" "x= at, y=at (1 -alphat) where a and alpha are positive constants and t is time . If the moment at which angle between velocity vecotrs and acceleration vectors is (pi)/(4) is given by (A)/(alpha) . Find the value of A .

If a and b are unit vectors and alpha is the angle between them , then a+b is unit vector when cos alpha =

One of the surfaces of a biconvex lens of a focal length 10 cm is silvered as shown in figure. Radius of curvature of silvered surface is 10 cm. At a given instant, if speed of object is 1m/s, then the speed of image at that instant is (10+alpha) m/s. What will be the value of alpha ? (mu=1.5)
