Three charges Q, +q and +q are placed at vertices of a right - angle isosceles triangle as shown blow. The net electrostatic energy of the configuration is zero, if the value of Q is:
+q
-2q
Potential Energy Of a System Of n Charge -
- wherein
For system of 3 charges.
Energy of photon
Since and as wave length increases M decreases, so Dm decreases
electron will be exite to n=4 since
Radius of atom will be 16 ao.
