A uniform solid cylinder of mass and radius is rolling without slipping on a horizontal surface with velocity . It encounters a sharp edge (step) of height (where ). Assume the cylinder does not slip at the edge and the collision with the edge is perfectly inelastic (the cylinder pivots about the edge). Which of the following statement(s) is(are) correct?
A parallel plate capacitor has plate area and separation . The space between the plates is filled with two dielectric slabs of dielectric constants and , each of thickness . A battery of emf is connected across the capacitor. Which of the following statement(s) is(are) correct?
A block of mass is attached to a spring of spring constant and is placed on a smooth horizontal surface. The block is displaced by a distance from its equilibrium position and released. Which of the following statement(s) is(are) correct?
Consider the following statements about the periodic properties of elements:
(I) The first ionization energy of nitrogen is greater than that of oxygen. (II) The electron affinity of fluorine is less negative than that of chlorine. (III) The electronegativity of carbon is greater than that of silicon. (IV) The atomic radius of sodium is greater than that of lithium.
A projectile is fired from the ground with an initial speed at an angle with the horizontal. The maximum height reached by the projectile is and the horizontal range is . If , then the angle of projection is:
