A particle with a charge of +7.4 C is separated from another charged particle with a charge of -3.6 uC by a distance of 1.4 m. Find the direction and the magnitude of electrostatic force
between the particles.

Orque can be calculated by multiplying the force (n) applied at 90? to the lever arm at a distance (m) from the pivot point (point of rotation), the compound si unit for the torque is n? m. if the force (at 90? to the lever arm) applied is 15 n and it is applied at 2.0 m from the pivot point (point of rotation), what is the torque on the lever?
