Ten identical masses (m each) are connected one below the other with $10$ strings. Holding the topmost string, the system is accelerated upwards with acceleration $g/2$. What is the tension in the 6th string from the top (Topmost string being the first string)? [Ans: $6\ mg$]
State the formula for acceleration due to gravity at depth ' $d$ ' and altitude ' $h$ ' Hence show that their ratio is equal to $\left(\frac{R-d}{R-2 h}\right)$ by assuming that the altitude is very small as compared to the radius of the Earth.
A charged metallic sphere A is suspended by a nylon thread. Another charged metallic sphere B held by an insulating handle is brought close to A such that the distance between their centres is 10 cm, as shown in figure (a). The resulting repulsion of A is noted (for example, by shining a beam of light and measuring the deflection of its shadow on a screen.) Spheres A and B are touched by uncharged spheres C and D respectively, as shown in figure (b). C and D are then removed and B is brought closer to A to a distance of 5.0 cm between their centres, as shown in figure (c). What is the expected repulsion of A on the basis of Coulomb’s law? Spheres A and C and spheres B and D have identical sizes. Ignore the sizes of A and B comparison to the separation between their centres.
