Question

binding energy of satellite is 4×10power 8 Joule . Its PE is
(a) -4×10power 8 j
(b) -8×10power 8 j
(c) 8×10power 8 j
(d)4×10power 8 j​

Answer 1

Answer:

Binding energy EB2=−4×108J   (since binding energy of satellite is negative)

∴ Potential energy of satellite P.E=2EB

P.E=2×(−4×108)=−8×108J
