A chain consisting of five links each with mass

A chain consists of five links each with mass 100gm as shown. It is lifted vertically upward with a constant acceleration of 2ms^(-2) .Then the force F exerted by the agent in lifting the chain is 'x'N. Then x is ...........

A chain consisting of 5 links each of mass 0.1 kg is lifted vertically up with a constant acceleration of 2.5m//s^2 . The force of interaction between 1st and 2nd links as shown:

A student tries to raise a chain consisting of three identical links. Each link has a mass of 300g. The three-piece chain is connected to a string and then suspended vertically, with the student holding the upper end of the string and pulling upward. Because of the student's pull, an upward force of 12 N is applied to the chain by the string. (a) Draw a free-body diagram for each of the links in the chain and also for the entire-chain considered a single body. (b) Use the results of part(a) Newton's laws to find (i) the acceleration of the chain and (ii) the force exerted by the top link on the middle link.

The equivalent capacitance of an infinite ladder of a circuit formed by the repetition of the same link consisting of identical capacitors, each with capacitance C , is .
