Solution
The correct option is D At t=2sec, the positions of both the pulses are separately shown in Fig. (a) and Fig. (b);
By the definition of Principle of superposition, displacements due to both the pulses from x=0tox=1 will get added up and the resultant shape of the pulse is shown in the Fig. (c).
Thus, option (d) is the correct answer.
