Question

Potential energy of a particle along x-axis varies as
shown in the figure. If the particle is released from
rest at a point on x-axis.
UA
(1) It will move in negative x-direction
(2) It will move with constant acceleration
(3) (v - x) graph for a particle is parabolic
(4) All of these
​

Answer 1

Answer:

(4)

Explanation:

1) this is an example of freely falling body from a height under the gravity

2) the potential is taken from ground to up (+ve)

3) x is taken from top to ground

4) hence graph of V-x graph of particle shows negative X-axis

5) since g is constant, acceleration is also constant

6) since v^2 = 2as, a parabolic equation, the (v-x) graph is a parabola

6) hence the answer is (4) (all)
