The wheel of radius R rolls wihtout slipping on horizontal rough surface and its centre O has an acceleration `a_(0)` in forward direction. A point P on the wheel is a distance r from O and angular position ` theta` from horizontal. Find the angle ` theta` for which point P can have zero acceleration in this position . A. `cos^(-1) ( r)/(R )`B. `tan^(-1) ( r)/(R )`C. `sin^(-1) ( r)/(R )`D. `cos^(-1) ( r)/(2R )`
