Polygon of force
This topic just builds on the previous Triangle of Forces.
Consider three forces A, B and C. A and B can be added by drawing a triangle to give a resultant.
If force C is joined to this resultant, a further or "new" resultant is created, which represents the effect of all three forces.
Now this procedure can be repeated many times; the effect is to produce a Polygon of Forces.
Again, the resultant can be derived mathematically.
Q. The kinetic energy of an electron 120 eV. Compute the de Broglie wavelength of electron. λ = h / √2mE λ = 6.626 X 10 -34 / √ 2 X 9.1 X 10 -31 X 120 X 1.6 X 10 -19
When the electron is known energy from external source, it goes to higher energy level. This process is called as excitation. The minimum energy needed to excite an atom is know
