Dear Student,

$w o r k d o n e = w o r k d o n e t o l i f t t h e w a t e r + w o r k d o n e t o l i f t t h e r o p e = 10 g h + (2 * 10) g h / 2 = 1000 + 1000 = 2000 J w o r k d o n e i s 2000 J R e g a r d s$

Dear Student, work done =workdone to lift the water +workdone to lift the rope =10gh+2*10gh/2=1000+1000=2000J work done is 2000 JRegards
