Question

the work required to fly a plane over a distance of 5 km is 25000 calculate the force required
a) 2N
b) 2KN
c) 5KN
d) 5N

Answer 1

Hi..
Hope this helps u!!

Answer 2

Given :

Displacement (S) = 5 Km = 5000 m

Work Required (W) = 25000 J

To Find :

Force

Solution :

We know, Work is said to be done when an object is displaced from its initial position under the action of a force.

    Work Done (W)  = Force (F) × Displacement (S)

⇒       25000           =  Force (F) × 5000

⇒      Force (F)         =  5 N

Therefore, the force required to fly a plane over a distance of 5 Km is found to be 5 N.

Hence, option (d) is correct.
