1But then, initially the radius you took as r is the radius of earth + atmosphere
right...[7][7]
stat1;if the atmospheree air suddenly condenses n form a thin layer on the surface of earththe duration of day ll increase

11no kalyan... initially we don't consider d atmosphere while taking d radius... v juzz take d solid spherical surface of earth into consideration... later when atmosphere condenses, an extra layer will form on earth's surface which increases it's radius...
i couldn't understand dis simple logic behind d question at first glance... :(
