Given below are two statements:

Given below are two statements: 
Assertion (A): If two particles are moving on the same circle in the same direction with different uniform angular speeds \(\omega_A \text{and } \omega_B\), then the angular velocity of B relative to A for an observer at the centre will be \(\omega_B-\omega_A\).
Reason (R): In a uniform circular motion the body is constantly in equilibrium.
  
1. Both (A) and (R) are True and (R) is the correct explanation of (A).
2. Both (A) and (R) are True but (R) is not the correct explanation of (A).
3. (A) is True but (R) is False.
4. Both (A) and (R) are False.
