Question

If symbols have their usual meanings, then which
of the following relations is true for equilibrium of a
particle?
(1) du/dr=0
(2)du/dr>0
(3)du/dt<0
(4)du/dr=k (k not equal to 0)​

Answer 1

Answer:

(1) du/dr=0

I hope this will help you... ❤️

Answer 2

Answer:

for equilibrium of particles F= 0

as we know F= - du/dr

so du/dr =0

so correct option is (1).
