    High School Subatomic Particles: Electrons, Protons & Charges

    can we explain this property just like we can explain the properties of light?

    High School Subatomic Particles: Electrons, Protons & Charges

    So, is it a meaningless question?

    I am still unable to understand it.:confused:

    High School Subatomic Particles: Electrons, Protons & Charges

    I want to know the definition of the charge and why do electrons & protons have charge.

    is their in electrons and protons that they acquire change? And what is the charge actually?

    Undergrad Is it necessary to talk about photons when discussing interference in light?

    Thanks for the video. but I;m still confused about what would be the observations on the screen.

    Undergrad Is it necessary to talk about photons when discussing interference in light?

    If we use a white light in Young's Double slit Experiment, instead of monochromatic light,What will happen?What could be observed on the screen? http://C:\Documents and Settings\Aditya\My Documents\My Pictures/untitled

    Undergrad Rolling Motion on Rough Surfaces

    I am confused on the same thing. Friction force occurs due to cold locking between the crests and troughs of rough surface and the surface of the body. So without such locking, how could it roll?

    Can Friction Be Zero for a Rolling Sphere on a Surface?

    Yes the surface is horizontal.Now, my opinion is if the surface suddenly becomes smooth then this body will start slipping i.e pure translational motion will start. So, Without friction, it will not roll. am I correct?

    Can Friction Be Zero for a Rolling Sphere on a Surface?

    Homework Statement A spherical body is rolling on a rough surface. then "the frictional force may or may not be zero" Is this statement is correct or not? we discussed about this in classroom. Some were saying it must not be zero and others were saying it may be zero. Which is correct?
