Torque

AP Physics 1· difficulty 1/5

Two equal forces of 20 N20~\text{N} are applied perpendicular to the same wrench, one at 0.10 m0.10~\text{m} from the bolt and one at 0.30 m0.30~\text{m}, in opposite rotational directions. The net torque is

  • A

    4 N⋅m4~\text{N·m}

    check_circle
  • B

    8 N⋅m8~\text{N·m}

  • C

    00

  • D

    2 N⋅m2~\text{N·m}

Explanation

Torques: 200.30=620 \cdot 0.30 = 6 and 200.10=220 \cdot 0.10 = 2, opposite directions → net 4 N⋅m4~\text{N·m}.
