1.	Torque applied is masimum when the angle between the directions of vectors r and F is(A) 90°(B) 180° (C) 0° (D) 45°
Answer» Correct option is: (A) 90° Torque = \(\overrightarrow r \times \overrightarrow F\) \(\tau = r \ F sin \ \theta\) .\(\because \ \theta = 90^\circ \) \(\tau_{max} = r \ F \ sin 90^\circ\) Correct option is: (A) 90°

Answer»

Correct option is: (A) 90°

Torque = \(\overrightarrow r \times \overrightarrow F\)

\(\tau = r \ F sin \ \theta\)

.\(\because \ \theta = 90^\circ \)

\(\tau_{max} = r \ F \ sin 90^\circ\)

Correct option is: (A) 90°
