When you find a solution to a problem and then keep using that solution despite the fact that other easier solutions are available, you are falling prey to ______.
The correct answer is The Einstellung Effect.
Justification - The meaning of the Einstellung Effect is when people tend to look at problems or situations with only one point of view and applying a solution which has been useful in various other situations, inspite of there being present several other easier solutions. For example - When a student keeps solving Math problems using a particular formula and ends up using the same formula to a relatively easier question which required simple steps and not the application of the formula.

You' will find that motion problems and other physics problems often have several variables and other pieces of information to keep track of. The best way to tackle such problems is to draw a pictorial representation of the problem that shows all of the important details. The following Tactics Box explains how to draw a pictorial representation of a motion problem. In the following sketches a_z is the train's acceleration; t_i and t_f denote, respectively the time instants when the...
