Which of the following statements (s) is/are correct ?

Options

A. In an inertial frame `W_("conservative") +W_("non-conservative") + W_("other -force") = K _(2) - K_(1)`
B. In a non - inertial frame : `W_("conservative") +W_("non conservative ") +W_("other -force") +W_("pseudo - force ") = K_(2) - K_(1)`
C. Work done by conservative forces is independent of path followed .
D. Work done by non - conservative forces depends on path followed .

Answer

A, B, C, D

Explanation

Work energy theorem is valid in both inertial as well as non - internal frame of reference , so options (a) and (b) are correct . Options (c ) and (d ) are also correct .
