An object is kept at 20 cm in front of a convex lens and its real image is formed at 60 cm from the lens. Find (1) the focal length of the lens (2) the image if the height of the object is 6 cm.

Find the focal length of a double-convex lens with R_(1) = 15cm and R_(2) = -25CM . The refractive index of the lens material n = 1.5

Find the focal length of a double-convex lens with R_(1) = 15cm and R_(2) = -25CM . The refractivwe index of the lens mateirla n = 1.5

A parallel beam of light falls successively on a thin convex lens of focal length 40 cm and then ono a thin convex lens of focal length 10cm as shown in figure. In figure, the second lens is an equi-concave lens of focal length 10cm and made of a material of refractive index 1.5. In both the cases, the second lens has an aperture equal to 1cm. Q. Compare the area illuminated by the beam of light on the screen, which passes through the second lens in the two cases. The ratio (A_(2)//A_(1)) will be

A vessel with a symmetrical hole in its bottom is Paste on a cart. The mass of the vessel and the cart is 1.5 kg . With what force F (in xx 10^(2)N) should the cart be pulled that the maximum amount of water remains in the vessel. The dimensions of the vessel are as shown in the figure. Given that b = 50 cm, c = 10 cm , area of base A= 40cm^(2), L = 20 cm, g = 10 m//s^(2).
