A spherical body moves with a uniform angular velocity around a circular path of radius. |
1. The body has no acceleration. |
2. The body has a radial acceleration \[{{v}^{2}}r\] directed towards the centre of the path. |
3. The body has a radial acceleration 2/5 \[{{v}^{2}}r\] directed away from the centre of the path. |
4. The body has an acceleration \[{{v}^{2}}r\] tangential to the path. |
Which of the statement(s) given above is/are correct? |
A) 3 and 4
B) Only 1
C) Only 2
D) None of these
Correct Answer: C
Solution :
[c] Statement 1 is incorrect as when a body moves with the H uniform angular velocity v there is an acceleration. Statement 2 is correct. The body has a radial acceleration towards the centre of the path. When a body moves in c straight line with constant velocity then there is an acceleration. Statement 3 and Statement 4 are incorrect.You need to login to perform this action.
