When a certain metal was irradiated with light of frequency 3.2 x 1016 Hz. Photoelectrons emitted had twice the kinetic energy as did photoelectrons emitted when the same metal was irradiated with light of frequency 2.0 x 101 ...
The sum of two forces is 16N. The resultant is normal to the smaller force and has a magnitude of 8N. then give the magnitude of the 2 force. please Explain ...
