I'm not too clear on the wording in the question but I think it is 90 degrees
Explanation:
I'm not sure if I completely understand the question on this and I'm a bit confused by the part of the question "....and that speed increases in
If a particle is travelling in circular motion, then its centripetal acceleration is equal to
I assume this acceleration is what is being referred to in the question as "....and that speed increases in
On this basis, for any particle travelling in circular motion, the instantaneous velocity at ay point is always at 90 degrees to the acceleration vector. The acceleration vector is always directed towards the centre of the circle of travel and the velocity is always tangential.
Explanation:
Given
Speed of the particle moving in a circular path is
Tangential acceleration acting on the particle
Radius of the circular path
The centripetal acceleration acting on the particle radially is
The resultant acceleration acting on the particle
If the resultant acceleration ‘a’ makes an angle
The direction of instanteneous veylocity vector is same as the direction of tangential acceleration.
Hence the resultant acceleration will also make
