A) At 3H/4 metre from the ground
B) At H/2 metre from the ground
C) H/6 metre from the ground
D) At H/4 metre from the ground
Correct Answer: A
Solution :
Key Idea: Since the body is released from rest initial velocity \[16\mu F\]. From equation of motion, we have \[{{E}_{a}}\] where g is acceleration due to gravity. We gave \[l\] \[{{E}_{q}}\] \[l,\] Height of body at time \[{{E}_{a}}\] is \[{{E}_{q}}\] Hence, height of body from the ground \[{{E}_{a}}=4{{E}_{q}}\]You need to login to perform this action.
