Take a glass rod, rub it with silk and hang it from a long silk thread. Take another glass rod, rub with silk and hold it near the rubbed end of the first rod. What happens to the rods?

Take a glass rod, rub it with silk and hang it from a long silk thread. Take another glass rod, rub with silk and hold it near the rubbed end of the first rod. What happens to the rods? Correct Answer They repel each other.

  • When a glass rod is rubbed with silk, the rod loses electrons, and silk gains electrons.
  • Therefore, the glass rod becomes positively charged due to the loss of electrons while silk becomes negatively charged due to the gain of an electron.
  • Another glass rod that is rubbed with silk is brought near the first rod, then they repel each other.
  • This is because both the rods are positively charged and similar charges repel each other.

Ram is playing with a thread and a brick of mass 2 Kg. He tied a thread one of its end with brick and another end with the roof. He holds the thread at 1 m below the roof and applying a force of 50 N. What is the tension that appeared in the upper part of the thread which is stick with the roof? Take (Tan 68° = 2.5; Cos 68° = 0.37; g = 10m/s2)
A hollow rod has frictionless inner walls. Inside the rod are two small spheres that are kept on either side of the centre of rod. The rod is rotated about its central axis which is perpendicular to the plane of rotation. If the rod had been rotated by an impulsive torque which gave it an instantaneous angular velocity of 5rad/s, what will be the angular velocity after some finite but long time ‘t’? Assume no external forces act on rod after the impulse. Also state what will happen to the spheres in the centre of the rod. The rod has a mass =2kg & length =10cm. The two spheres have a mass =1kg each.

The base of a right pyramid is a square of side 10 cm. 4 rods with maximum possible length have been kept in the pyramid. The volume of the pyramid (without keeping the rods inside) is 400 cm3. The radius of the base of all the rods is 0.7 cm. What will be the approximate volume of the remaining part of the pyramid (when rods are kept inside the pyramid)?
Three rods, one made of silver (l = 420W/m K), second made of aluminum (k = 210W/m K) and the third made of iron (k = 70W/m K) are coated with a uniform layer of wax all around. The rods are placed vertically in a boiling water bath with 250 mm length of each rod projecting outside. If all the rods are having following dimensions i.e. diameter = 15 mm and length = 300 mm and have identical surface coefficient 12.5W/ m2 K, work out the ratio of lengths up to which wax will melt on each rod
