Circular motion - marble in bowl

[Thanuka]

Can anyone please answer this question

1.A glass marble of mass m is moving int a horizontal circle round the inside surface of a smooth hemispherical bowl of radius r. The centre of the circle is at a distance 1/2r below the centre of the bowl. (i) Find the magnitude of the reaction between the marbel and the bowl (ii) and the speed of the marble.

Note down the two forces acting on the marble.
Marble is moving in a horizontal circle without slipping along the bowl.
So identify equal and opposite camponents of the two forces acting on the marble.
Other camponents of the two forces adds up to give the normal reaction.
