Number of electrons in one coulomb of charge will be
$5.46 \times {10^{29}}$
$6.25 \times {10^{18}}$
$1.6 \times {10^{ + 19}}$
$9 \times {10^{11}}$
When ${10^{19}}$ electrons are removed from a neutral metal plate, the electric charge on it is
How can the neutral body be charged electrically ?
Why only electron can transfer from one body to another body in frictional electrics ?
Discuss the types of electric charges by rubbing appropriate non-conductors. Which scientists gave their names ?
What is called polarity of electric charge ?
