Two very small conducting spheres, each of mass 1.0x10 kg are suspended at a common point by very thin (weightless') non-conducting threads of length 0.2 m. a charge +q is placed on each sphere. suspending threads make an angle of 10. assume g-9.8 m/s2 and negligible mass for the threads. a) draw labelled force diagrams for the system b) calculate the value for q

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
