A particle of mass m describes a horizontal circle of radius 0.24m inside a smooth hemispherical bowl of internal radius 0.25m which is held with the rim horizontal. A light string tied to the particle passes through a smooth hole at the bottom of the bowl and supports another particle of mass m which hangs in a rest position. Show that the speed of the former particle is almost 4m/s


Can anyone draw me the actual diagram + forces diagram?
I have no idea about this question
THANKSS!

Oh i got the ^ question now!



but can anyone do the following question for me?
thanks


Particles P and Q of masses 3kg and 1kg respectively are connected by a light inextensible string of length 2m passing through a small hole O in a smooth horizontal table. P describes a circle on the table with a uniform speed of g/3 rad/s and Q moves as a conical pendulum of semi-vertex angle 日 with plane QOP always vertical. Find 日 and the length of OP.
