A cuboidal water tank is 6 m long, 5 m wide and 4.5 m deep. How many litres of water can it hold ? (1m^(3)=1000l)

Two equal and opposite charges of masses m_(1) and m_(2) are accelerated in an uniform electric field through the same distance. What is the ratio of their accelerations if their ratio of mass is (m_(1))/(m_(2))= 0.5 ?
