Two spheres of radii 1 cm and 2 cm have been charged with `1.5 xx 10^(-8) and 0.3 xx 10^(-7)` coulomb of posiitve charge. When they are connected with a wire, charge :

Two spheres of radii 1 cm and 2 cm have been charged with 1.5 xx 10^(-8)C and 1.5xx10^(-7)C , respectively. If they are connected with a wire, will there be any charge flow? Explain.

Two spheres of radii 1cm and 2 cm have been charged with 1.5 xx 10^-8C and 0.3 xx 10^-7C respectively. If they are connected with a wire will there be any charge flow? Explain.

Two metallic spheres of radii 1 cm and 3 cm are given charges of -1 xx 10^(-2) C and 5 xx 10^(-2) C , respectively . If these are connected by a conducting wire , the final charge on the bigger sphere is
