Light of intensity l is incident perpendicularly on a perfectly reflecting plate of area A kept in a gravity free space. If the photons strike the plate symmetrically and initially the springs were at natural lengths, what is the maximum compression

The ball strikes the block and sticks to it. Find the maximum compression of spring. ( L : natural length of spring)

A narrow monochromatic beam of light of intensity I is incident on a glass plate. Another identical glass plate is kept close to the first one and parallel to it. Each plate reflects 25% of the incident light and transmits the remaining. Calculate the ratio of minimum and maximum intensity in the interference pattern fromed by two beams obtained after reflection from each plate.

Block A of mass m is placed on a plank B . A light support S is fixed on plank B and is attached with the block A with a spring of spring constant K . Consider that initially spring is in its natural length. If the plank B is given an acceleration a, then maximum compression in the spring is (xma)/(k) . Find the value of x (All the surface are smooth)

A parallel beam of light of intensity I is incident on a glass plate. 25% of light is reflected in any reflection by upper surface and 50% of light is reflected by any reflection from lower surface. Rest is refracted The ratio of maximum to minimum intensity in interference region of reflected rays is

A spring having a spring constant k is fixed to a vertical wall as shown in Fig. A block of mass m moves with velocity v torards the spring from a parallel wall opposite to this wall. The mass hits the free end of the spring compressing it and is decelerated by the spring force and comes to rest and then turns the spring is decelerated by the spring force and comes to rest and then turns back till the spring acquires its natural length and contact with the spring is broken. In this process, it regains its angular speed in the opposite direction and makes a perfect elastice collision on the opposite left wall and starts moving with same speed as before towards right. The above processes are repeated and there is periodic oscillation. Q. What is the maximum compression produced in the spring?

Two blocks having masses 8kg and 16kg are connected to the two ends of a light spring. The system is placed on a smooth horizontal floor. An inextensible string also connects B with ceiling as shown in the figure at the initial moment. Initially the spring has its natural length. A constant horizontal force F is applied to the heavier block as shown. What is the maximum possible value of F so the lighter block doesn't loose contact with ground?

A narrow monochromatic beam of light of intensity I is incident on a galss plate as shown in figure. Another identical glass plate is kept close to the first one & parallel to it. Each glass plate reflects 25% of the light incident on it % transmits the remaining find the ratio of the minimum & the maximum intensities in the interference pattern formed by the two beams obtained after one reflection at each plate.
