Find the torque of a force F = 7i + 3j+5k about the origin the force acts on a particle whose position vector is r= i+ j +k Share with your friends Share 1 Hempushp Katara answered this Dear Student Force (F→) = (7i + 3j+5k) and Point ( r→) = ( i+ j +k ). So, torque (τ) = r→×F→ ⇒ τ =i^j^k^735111 ⇒ τ =(3 - 5)i^ - (7+ 5)j^+ (7 -3)k^ = (- 2i^- 12j^ +4k^ ) and the magnitude of the torque be = 22+122 +42 = 164 =241 Regards 1 View Full Answer
