when A current-carrying conductor is placed in A magnetic field due to the interference of both magnetic fields,the field is made variable so a force will be induced on the Conductor. so my question is, If an Ac current is passed through conductor it will have variable magnetic field will it...

The experiment is you supply light (photons) on a metal surface to release e- then they said 240 nm wavelength of radiation gives Max Photoelectric current.After that they said Intensity is constant and wavelength is reduced causing the current to decrease but I simply can't understand why

In my book it is stated.When you keep the intensity constant and decrease the wavelength the photoelectric current decreases but I can't understand why? I thought it would stay the same since photoelectric current depends on the intensity of photons as more number oh photons means more e- released

Hello, I uploaded an image of the question so it becomes clear my main doubt is which procedure should I follow 1) total object weight*PERP. Distance to toppling point=Moment of cylinder+moment of cone 2) moment of cylinder ≥ moment of cone I tried doing method two since they asked for least...
