R1 = R, R2 = 2R
NOW THE INITIAL WORK DONE (W) IS = 8πR²s
and FINAL WORK DONE (W)= 8π[R2² - R1²]s
8π[4R² - R²]S
3 x 8πR²s = so W = 3W AS THE W IS EQUAL TO 8πR²S
NOW THE INITIAL WORK DONE (W) IS = 8πR²s
and FINAL WORK DONE (W)= 8π[R2² - R1²]s
8π[4R² - R²]S
3 x 8πR²s = so W = 3W AS THE W IS EQUAL TO 8πR²S
