Question

(c) horizontal plane under the action of a constant A particle is moving unidirectionally power supplying energy source. The displacement (s)-time (1) graph that describes the motion of the particle is (graphs are drawn schematically and are not to scale): S S (b) S S (d)​

Answer 1

Answer:

Correct option is

B

option

Constant power,

P=

dt

F

.d

s

=

F

.

v

=constant

Now, will by dimensional analysis

[F].[v]=constant

[MLT

−2

].[LT

−1

]=constant

L

2

T

−3

=constant

d

2

∝t

3

d∝t

3/2

displacement∝(time)

3/2

From the above equation,

The correct option is B.
