1.	What is ratio of surface energy of 1 small drop and 1 large drop, if 1000 small drops combined to form 1 large dropA. `100 :1`B. `1000 :1`C. `10 : 1`D. `1: 1000`
Answer» Correct Answer - D Volume of large drop `= 1000 xx` Volume of smaller droplets `(4)/(3) pi R^(3) = 1000 xx (4)/(3) pi r^(3) rArr R = 10 r` Surface energy of small drop, `E_(1) = S xx 4pi r^(2)` Surface energy of large drop, `E_(2) = S xx 4pi (10 r^(2))` `:. E_(1)//E_(2) = 1//100`
