The radii of two bubbles are r1 and r2 . In isothermal condition, two meet together in vacuum. then the radius of the bubble is given by:
The radii of two soap bubbles are r 1 and r 2. In isothermal conditions, two meet together in vaccum. Then the radius of the resultant bubble is given by
If the sum of the areas of two circles with radii R1 and R2 is equal to the area of a circle of radius R, then
If the sum of the areas of two circles with radii R1 and R2 is equal to the area of a circle of radius R then
(a) R1+R2=R
(b) R1+R2>R
(c) R21+R22<R2
(d) R21+R22=R2
