A simple pendulum is made of bob which is a hollow sphere full of sand suspended by means of a wire. If all the sand is drained out, the period of the pendulum will

Suppose the bob in a simple pendulum is a hollow sphere with a small hole at the bottom. The sphere is filled with water and is made to oscillate. What happens to the period ?

The time period of a simple pendulum is 2s. If its length is increased by 4 times, then its period becomes (a) 16s (b) 12s (c) 8s (d) 4s

A simple pendulum is made of a hollow sphere having a small hole in the bottom. The pendulum is made to vibrate after filling it with water. STATEMENT -1 : Time period of pendulum will first increase upto certain maximum value and then decrease are return to its initial minimum value. and STATEMENT-2 : The effective length of osciallation of a simple pendulum first increases andthen decreases toreturn to its initial minimum value

A uniform metallic rod rotates about its perpendicular bisector with constant angualr speed. If it is heated uniformly to raise its temperature slightly, then a) its speed of rotation increases b) its speed of rotation decreases c) its speed of rotation remains same d) its speed increases because its moment of inertia increases

A hollow sphere is taken as bob of a simple pendulum. This hollow sphere is filled with fine sand. There is a small hole at the bottom of this sphere through which the fine sand leaks out. How does the time period of this simple pendulum alter? Discuss.

A simple pendulum with a metallic bob has a time period T.The bob is now immersed in a non-viscous liquid and oscillated . If the density of the liuid is (1)/(4) that of metal , what will be the time period of the same pendulum? Hint : If the solid bob of the pendulum has relative densty D and has been submerged in a non-viscous liquid of relative density rho then effective acceleration due to gravity g' = g-(g)/(n) where n = (D)/( rho)

Assertion : The bob of a simple pendulum is a ball full of water, if a fine hole is made in the bottom of the ball, the time period first increases and then decreases. Reason : As water flows out of the bob the weight of bob decreases.

Assertion: If bob of a simple pendulum is kept in a horizontal electric field, its period of oscillation will remain same. Reason: If bob is charged and kept in horizontal electric field, then the time period will be decreased.

The period of a simple pendulum whose bob is hollow metallic sphere is T . The period is T_(1) when the bob is filled with sand, T_(2) where it is filled with mercury and T_(3) when it is half filled with mercury Which of the following is true?
