For a charged particle moving from point P to point Q, the net work done by an electrostatic field on the particle is independent of the path connected point P to point Q.
The net work done by a conservative force on an object moving along a closed loop is zero.

The above is a plot of binding energy per
nucleon Eb, against the nuclear mass M; A, B,
C, D, E, F correspond to different nuclei.
Consider four reactions :
(i) A + B → C + e
(ii) C → A + B + e
(iii) D + E → F + e
(iv) F → D + E + e
where e is the energy released ? In which reaction is e positive ?

A (i) and (iv)
B (i) and (iii)
C (ii) and (iv)
D (ii) and (iii).

A p–n junction (4) shown in the figure can act as a rectifier. An alternating current source (V) is connected in the circuit.
