Find the acceleration produced by a force of 5 N acting on a mass of 10 kg.
Advertisements
उत्तर
We know that:
Force = mass × acceleration
= m × a
Here, mass, m = 10 kg
force, F = 5 N
Putting these values in the above formula, we get:
5 N = 10 × acceleration
⇒ acceleration = `5/10`
⇒ acceleration = `0.5 "m/s"^2`

A plumb bob is hung from the ceiling of a train compartment. If the train moves with an acceleration 'a' along a straight horizontal track , the string supporting the bob makes an angle tan−1 (a/g) with the normal to the ceiling. Suppose the train moves on an inclined straight track with uniform velocity. If the angle of incline is tan−1 (a/g), the string again makes the same angle with the normal to the ceiling. Can a person sitting inside the compartment tell by looking at the plumb line whether the train is accelerating on a horizontal straight track or moving on an incline? If yes, how? If not, then suggest a method to do so.
