9yeah d can be correct
eg a=kx
v/a
q1 two particles describe the same circle of radius a in the same sense with the same speed v .wat sr der relative angular velocity .is it 0 or v/a
q2if the acceleration of a particle is a function of distance as a =f(x)
a)velocity must be the fn of displacement
b)velocity vs displacement graph can not be a straight line
c)velocity may be a fn of displacement
d)acc displacement graph may be a straight line
ans is c my doubt is why d is a false statement

9take for example
wen pts are diametrically opp then w =2v/2a =v/a
similarly u can show that when pos vectors are inclined at @ for particles
vrel = 2vsin@/2
R = 2asin@/2
