The component of velocity perpendicular to the surface will become 0. So, the particle will move upwards along the surface

Thanks @Rade_Woosh @Aastik_Guru , got it. Woh plane pe hi move karenga.

but isse mera answer kuch aur aa rha h.Shayad I am doing calculation error

do give it a try…i am not getting it. :sweat_smile:

That v/3 for both is correct right
Given in the bottom left is.the key I presume
@mihir

yes that’s the answer can you send the solution…

just give me few mins
in short i ll tell u the accelerations for both block turn out to be the same and thus after using constraints there accelerations are 1/3 of the one being pulled thus in time t vel becomes v for string and v/3 for blocks
i ll send sol in some time
