In a non - uniform circular motaion the ratio of tangential to radial acceleration is (where, r= radius of circle, v= speed of the particle, `alpha=` angular acceleration)
A
`alpha = (av)/(omega)`
B
` alpha =(vomega)/(a)`
C
`alpha =(omega)/(av)`
D
`alpha =(aomega )/(v)`
Text Solution
Verified by Experts
The correct Answer is:
D
`a= ralpha therefore alpha =(a) /( r ) ` ` "But " v = r omega therefore =(v) /( omega )` ` therefore alpha = (a) /((V)/(omega))=(a omega)/( v) `

In a non uniform circular motion, the acceleration on the particle is
Non-uniform circular motion: radial & tangential acceleration| Radius of curvature
Non-uniform circular motion: radial & tangential acceleration| Radius of curvature
In nonuniform circular motion, the linear acceleration vec a , the angular acceleration, vec alpha , the angular velocity vec v the radius vector vec r and the angular velocity vec omega at any instant are related by the vector equation,
The tangential and radial acceleration of a particle are a(t) and a(r) respectively. The motion of a particle is circular if
Acceleration in circular motion|| Tangential acceleration|| Radial acceleration|| Shape OF path & net Acceleration
Assertion:- A particle is moving in a circle with constant tangential acceleration such that its speed v is increasing. Angle made by resultant acceleration of the particle with tangential acceleration increases with time. Reason:- Tangential acceleration =|(dvecv)/(dt)| and centripetal acceleration =(v^(2))/(R)
