a particle is moving in a cirular orbit with a constant tangentialacceleration ,after a certain time t has elapsed afterthe begining of mtion ,the angle between the total acceleration w and the irection along the adius R becomes equal to 45 ,what is the ngular acceleration of the particle

Let the tangential acceleration be a and initial ang vel be wi. Now ang vel at time t(w) will vary as w=wi=at. At time t centripetal acceleration is =R(w*w). Tangential acceleration =a. tan inverse of a and R(w*w) should b1 implying that they are equal.


So on solving the equality you should probably get the correct answer
