A block having mass `m = 4 kg` and charge `q=50 muC` is connected to a spring having a force constant `k=100 N'/'m`. The block lies on a frictionless horizontal track and a uniform electric field `E=5×10^5` V/m acts on the system as shwon in figure. The block is released from rest when the spring is unstretched (at `x = 0`) (a) By what maximum amount does the spring expand? (b) What is the equilibrium position of the block?

A great physicist of this century (P.A.M. Dirac) loved playing with numerical values of Fundamental constants of nature. This led him to an interesting observation. Dirac found that from the basic constants of atomic physics (c, e, mass of electron, mass of proton) and the gravitational constant G, he could arrive at a number with the dimension of time. Further, it was a very large number, its magnitude being close to the present estimate on the age of the universe (~15 billion years). From the table of fundamental constants in this book, try to see if you too can construct
