(a) Is the proportionality constant 'k' always taken as 1 in all numericals of physics or does it take different values? (2) According to Newtons second law, force is proportional to the product of mass and acceleration..in these numericals..if 'k' assumes the value of 1 (MKS system) then what is the value of 'k' in the CGS system?

(1) no the value of costant depends on the experimental result or the choice of units.
 
(2) in the 2nd law, the constants value is 1
     and in mks system the value will be changed by changing the units of mass and acceleration if we want to get the answer of force in units of Newton.
there k will be 105

Questions 23-25 are based on the information given below. Read the information and answer the questions that follow:A bob of mass ‘m’ is suspended by a string, g be the acceleration due to gravity the bob.When the bob is stationary, the tension ‘T’ in the string is T=mg.When the bob is pulled up with an acceleration ‘a’ the tension in the string is given by T= m (g + a)When the bob is allowed to move down with an acceleration ‘a’, the tension T in the string is given byT= m (g –a)
