Hola User_________________
Here is Your Answer.....!!!!!
____________________________
☆Actually welcome to the concept of the Kinematics of the bodies .....
☆Basically if we see here the given condition ......
☆we can find that there is no friction between the end of the rod at the top end and also the lower end ......
☆So if we apply here the concept of the Rotatinal dynamics ....then we be get that. ..
☆As the body moves more and more steeper .....the torque increses and as there is no friction ...the rod moves faster as it leans more towards ground ....
■THUS THE SPEED OF THE LOWER END INCRESES AT THE CONSTANT RATE ...

ankushsingh795:
but answer is option 3
okay
actually the speed is faster of upper end also ....but when the rod is about to fall ....the both speed simultaneously decreses and when the rod touches the ground ...the rod is at stationary and its velocity vanishes ...
