The rolling of the cylinder is termed as perfect rolling only when the cylinder is rolling at a constant velocity. Also the rolling should be along the rigid surface. The normal forces are acting perpendicular to the surface of the rolling. And for rolling equation Wa/r is generally used.

Answer:
The equation Wa/r is commonly used in rolling frictional calculations. Let's break down each component of the equation:
W: Weight of the body
The variable W represents the weight of the body. Weight is the force exerted on an object due to gravity and is typically measured in Newtons (N). In this equation, the weight is denoted by W.
a: Coefficient of rolling friction
The variable a represents the coefficient of rolling friction. It is a dimensionless number that quantifies the amount of friction between two objects in contact during rolling. Rolling friction is the resistance encountered when an object rolls over a surface. The coefficient of rolling friction depends on various factors such as the materials in contact, surface roughness, and the load on the object.
r: Radius
The variable r represents the radius of the rolling object. The radius is the distance from the center of the object to its outer edge. It is typically measured in meters (m) or centimeters (cm), depending on the units used in the problem.
P: Force
The variable P represents the force acting on the object. This force can be applied externally or can be the result of other forces acting on the object, such as gravity or a driving force. The force is typically measured in Newtons (N) and can be in any direction.
Explanation:
In the equation Wa/r, the weight of the body (W) is divided by the radius (r) and multiplied by the coefficient of rolling friction (a). This equation is used to calculate the rolling frictional force (P) acting on the body.
When an object rolls over a surface, there is a resistance to its motion due to the friction between the object and the surface. This resistance is known as rolling friction. The equation Wa/r helps to determine the magnitude of this rolling frictional force.
By multiplying the weight of the body by the coefficient of rolling friction and dividing it by the radius, we can find the force acting on the body due to rolling friction. This force can be used to analyze the motion and behavior of the rolling object.
Therefore, the correct answer is option 'A': P is the force, W is the weight of the body, r is the radius, and a is the coefficient of rolling friction, all in their normal powers.
