Assertion : If we plot potential versus x- coordinate graph along the x-axis, then field strength is zero where slope of `V -x` graph is zero.
Reason : If potential is function of x- only then
`E = - (dV)/(dx)`

In a displacement versus time graph __________ is taken on the x-axis

If the graph would be parallel to x-axis, the its number of zeros for the graph would be:

Assertion : The field strength at the centre of a ring is zero Reason : At the centre of the ring, slope of V-r graph is zero.\

Assertion : The field strength at the centre of a ring is zero Reason : At the centre of the ring, slope of V-r graph is zero.\

Consider the following a-t graph for a particle moving along the x-axis. If the initial velocity is zero, sketch the v-t graph.

Position (x) versus time (t) graph of a particle is as shown. The velocity is zero at?

If the distance is plotted on the x-axis and kinetic energy is plotted on the y-axis, then the slope of the graph so obained is proportional to

Assertion : If gravitational potential at some point is zero, then gravitational field strength at that point will also be zero. Reason : Except at infinity gravitational potential due to a system of point masses at some finite distance can't be zero.
