Question

A desk with a mass of 100Kg is transported in an elevator which is accelerating upwards at 2m/s^2. what is the reaction force on the object by the floor of the elevator?

Answer 1

Given :

• Mass of the desk (m) = 100 kg
• Acceleration upwards (a) = 2 m/s²

To Find :

• Force by the elevator (f)

Solution :

It's given that, the object of mass 100kg is transported in an elevator which is accelerating upwards at 2m/s².

Formula to be used ,

$\underline{\boxed{\sf Force = Mass \times Acceleration}}$

Given that ,

• Mass = 100 kg
• Acceleration = 2m/s²

Substituting values ,

$\Rightarrow \sf F = M \times a$

$\Rightarrow \sf F = 100 \times 2$

$\Rightarrow \sf F = 200 N$

Required Answer :

Reaction Force on the object by the floor of the elevator is $\underline{ \sf 200 N}$
