Question

A force of $1875$ dyne acts on a rigid body, such that perpendicular distance between fulcrum and point of application of force is $20cm$. Calculate the moment of force.

• A. $3750dynecm$
• B. $37500dynecm$
• C. $3500dynecm$
• D. $375000dynecm$

Answer 1

The correct option is B $37500dynecm$

Force $F=1875dyne$

Distance between force and fulcrum $r=20cm$

Torque $\tau =rF=20\times 1875=37500dynecm$
