A parellel combination of 0.1Mohms resistor & a 10micro farads capacitor is connected across a 1.5V source of negligible resistance.The time (in seconds) required for the capacitor to get charged up to 0.75V is appoxmately


infinty


loge2


log102


0


ans is 0

since d connection is parallel


d capacitor will charge widin an instant


so d ans is zero
nobody is wrong
even a stopped clock is right twice a day

since the connections are in parallel and so there is CONSTANT pd across the capacitor hence it will almost take negligible time to get charged...
hope u get it
rate if u like
