Explanation Given information: The radius of the cylinder is r . Calculation: Show the position of the particle inside the cylindrical surface as in Figure (1). Take the datum at position 2. For position 1: Write the expression for the displacement ( x ): x = R ( 1 − cos θ m ) Write the expression for kinetic energy ( T 1 ) : T 1 = 0 Write the expression for potential energy ( V 1 ) : V 1 = W x Substitute R ( 1 − cos θ m ) for x . V 1 = W R ( 1 − cos θ m ) ( 1 − cos θ m = 2 sin 2 θ m 2 ) = W R sin 2 θ m 2 For small oscillation sin θ ≈ θ . V 1 = W R θ m 2 2 For position 2. Write the expression maximum velocity ( v m ) : v m = R θ ˙ m Here, θ ˙ m is maximum angular velocity. Write the expression for kinetic energy ( T 2 ) : T 2 = 1 2 m v m 2 Substitute R θ ˙ m for v m . T 2 = 1 2 m ( R θ ˙ m ) 2 Write the expression for potential energy ( V 2 ) : V 2 = 0 Write the expression for weight ( W ): W = m g Write the expression for maximum angular velocity ( θ ˙ m ) :
