The binding energy of a 60 kg body is 6.732 giga joules but according to the einstein's mass energy equation it posses energy of 540×10(power)16 joules so where does the remaining energy go??????????

Dear Student,
Here you are getting confused with concept of mass defect. Actually mass defect is there because of attraction forces which acts in between the nuclear particles. SO because of this energy gets released. and enegy of the body is lesser than the ecpacted theoritial value.
I hope you understood !

thanks
