| Re: KCET Physics Questions
On your demand here I am providing question paper of Physics subjects for KCET exam preparation Question1. The Physical quantity having the same dimensions as Planck’s constant h is? Boltzmann constant Force Linear momentum Angular momentum Question2. When light is incident on a diffraction grating the zero order principal maximum will be… One of the component colors Absent Spectrum of the colors White Question3. H-polaroid is prepared by… Stretching polyvinyl alcohol and then heated with dehydrating agent Stretching polyvinyl alcohol and then impregnating with iodine Orenting herpathite crystal in the same direction in nitrocellulose By using thin tourmaline crystals Question4. Out of following four dimensional quantities, which one qualifies to be called a dimensional constant? Acceleration due to gravity Surface tension of water Weight of a standard kilogram mass The velocity of light in vacuum Question5. From the top of the tower two stones, whose masses are in ratio 1:2 are thrown- one straight up with an initial speed u and the second straight down with the same speed u. Then neglecting air resistance… The heavier stone hits the ground with higher speed The lighter stone hits the ground with higher speed Both the stones will have the same speed when they hit the ground The speed can’t determine with the given data Question6. A student unable to answer a question on newton law of motion attempts to pull himself up by tugging on his hair. He will not succeed… As the force exerted is small The frictional force while gripping, is small Newton’s law of inertia is not applicable to living beings As the force applied is internal to the system Question7. A truck accelerates from speed v to 2v. Work done during this is… Three times as the work done in accelerating it from rest to Same as the work done in accelerating it from rest to Four times as the work done in accelerating it from rest to Less than the work done in accelerating it from rest to Question8. Pick out the Wrong statement from the following Lateral shift increases as the angle of incidence increases. Lateral shifts increases as the value of refractive index increases. Normal shifts decreases as the value of refractive index increases. Both normal shifts and lateral shifts are directly proportional to thickness of the medium. KCET Physics Questions paper      |
