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

Answers : (1)


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

A body of mass ‘m’ is joined to a very heavy body by a light string passing over a light pulley.Both bodies are free to move.Total downward force on the pulley? Ans.4mg
Dear student, Please tell us the mass of the heavy body else we cannot find the net downward force on the pulley. The reason we need the mass of the heavier body as well because the net...

Yes,but the answer given was 4mg....I doubt the answer because ‘m’ is the small mass and how the tension can be in small mass terms when it is given that the other body is a very heavy mass?

the answer will be independent of the frame, so the magnetic field will remain the same.
But why it will be frame independent.
