Questions
Select the correct statement. In a conservative force field
a
if the potential energy of a body is zero, net force acting on the body must be zero
b
if potential energy of the body is minimum, net force acting on the body may not be zero.
c
if potential energy of a body is zero, net force acting on the body may not be zero
d
none of the above statements is correct
detailed solution
Correct option is C
Conservative force acting on a body is given by F=−dUdr. So if U is zero, rate of change of potential energy with displacement may not be zero. Also when U = 0, rate of change of potential energy with displacement may not be zero.Talk to our academic expert!
