Homework Statement
A uniform chain of total length 'a' has a portion 0<b<a hanging over the edge of a smooth table AB. Prove that the time taken for the chain to slide off the table if it starts from rest is (a/g)1/2*ln(a+((a2-b2)/b)1/2)
well... to be honest, a laundry list is exactly what i wanted. eliminating every other force in the nuclear domain and gravity outside the atom, i was left only with the electromagnetic force. And that's what made me wonder whether these forces are nuthing but electromagnetic forces or not...
Homework Statement
Can anyone tell me what are the different types of electromagnetic forces? i know friction, non-penetrability of solids etc. are phenomenons of the electromagnetic force. Similarly are viscous force, cohesive force, adhesive force results of electromagnetic force...
Homework Statement
A suspension wire is given and the problem is to find out it's rigidity modulus. Say the wire is of length 'l' and a mass 'm' is suspended with the help of the wire.
Homework Equations
All i know is Young's modulus or 'Y' is Y=stress\strain
