A) Heavy ball
B) Light ball
C) Both simultaneously
D) Will depend upon the density of the balls
Correct Answer: C
Solution :
We know that gravity is a universal force with which all bodies are attracted towards the earth. Hence, g is same for both the balls. Also, if t is the time taken by the balls to reach the ground, then from equation of motion \[s=ut+\frac{1}{2}g{{t}^{2}}\] \[\Rightarrow \] \[t=\sqrt{\frac{2(S-ut)}{g}}\] Since, s, u and g are same for both, hence time taken by both the balls is same.You need to login to perform this action.
