alleryStart learning →Angular velocity omega in terms of time period T:
- omega = 1/T
- omega = 2π/T
- omega = T
- omega = T/2π
Show answer and solution
Correct answer: B. omega = 2π/T
omega = 2π/T = 2πf. SI unit: rad/s.
T is time for one full rotation; one rotation is 2π rad.

Worked practice questions
As per your syllabus, the CM of a continuous distribution is given by which integral?
- R = ∫ dm / M only
- R = ∫ r dm only
- R = (1/M) ∫ r dm
- R = M ∫ r dm
Show answer and solution
Correct answer: C. R = (1/M) ∫ r dm
Your syllabus: R_cm = (1/M) ∫ r dm, where dm is the mass element.
Generalisation of discrete sum.
As per your syllabus, the vector product is which property algebraically?
- Anticommutative (A×B = −B×A)
- Commutative (A×B = B×A)
- Distributive but symmetric
- Distributive but commutative
Show answer and solution
Correct answer: A. Anticommutative (A×B = −B×A)
Your syllabus: A × B = −B × A. Distributive but not commutative.
