Two forces 3N and 2N are at an angle Ө such that the resultant is R the first force is now increased to 6N, and the resultant becomes 2R. the value of Ө is
Correct answer: C. Angular acceleration
- A. Acceleration
- B. Linear acceleration
- C. Angular acceleration
- D. Direction of motion of the body
Explanation
Torque is a measure of the tendency of a force to rotate an object about an axis. It is related to angular acceleration (α) through the equation:τ=Iαwhere τ is the torque, I is the moment of inertia, and α is the angular acceleration

About Force and Motion
Displacement, velocity and acceleration describe motion, including the horizontal and vertical components of projectile motion. The chapter connects these quantities with Newton's laws, momentum and impulse, then applies conservation of momentum to collisions, distinguishing elastic collisions from inelastic ones.
