Eight drops of same radius
WebAnswer (1 of 2): Since the volume of the big drop is equal eight times of the volume of the smaller drop so, (4/3)πR³ =8× (4/3)πr³ => R = 2r , R is the radius of the big drop and r … http://www.khullakitab.com/physics/pastpapers/grade-11/34/pastpapers

Did you know?
WebMay 6, 2008 · No, because although there is twice as much mass, the radius is larger so you are farther from the center. For the spherical raindrops, the potential at the surface of the drop is due to the charge and the radius of the drop, and both of these will increase when the eight drops combine. May 6, 2008. #7. WebApr 1, 2024 · According to the question, the radius of eight drops is r. So, we can say, the volume is \[\dfrac{4}{3}\pi {r^3}\].Total volume is, \[\dfrac{4}{3}\pi {r^3} \times 8\] which is …
