A positively charged glass rod is brought close to a neutral sphere that is supported on a nonconducting plastic stand. Sketch the distribution of charges on the sphere if it is made of:
a) Aluminum
b) Non-conducting plastic

  • physics -

    a)Aluminum: the electrons in the sphere would rise towards the positively charged glass rod making the top part of the sphere negative and the bottom part positive

    b) Non conducting matierial: nothing would happen the sphere would still be neutral
