Charge on $\alpha $ - particle is
$4.8 \times {10^{ - 19}}\,C$
$1.6 \times {10^{ - 19}}\,C$
$3.2 \times {10^{ - 19}}\,C$
$6.4 \times {10^{ - 19}}\,C$
When a glass rod is rubbed with silk, it
A conductor has $14.4 \times {10^{ - 19}}coulombs$ positive charge. The conductor has(Charge on electron $ = 1.6 \times {10^{ - 19}}coulombs$)
Why the light particles like pith balls attract towards charged rod ?
How can object be charged with contact ?
