A 267.5 N unbalanced force applied to push a stuffed chair across the room, causing an acceleration of 4.2
m
s2
. What is the mass of the chair?
A) 26.75 kg
B) 63.69 kg
C) 263.3 kg
D) 1123.5 kg

The answer for the following problem is mentioned below.

Explanation:

Force(F):

The push or pull on an object resulting from the object's interaction with another object.

The SI unit of force is N (newtons)

The formula to calculate the force:

F = m × a

Acceleration (a):

It is a vector quantity.

The rate at which an object changes its velocity

The SI unit of acceleration is m/s^2

Given:

Force (F) = 267.5 N

acceleration (a) = 4.2 m/s^2

To calculate:

mass of the chair (m)

We know;

According to the equation;

F = m × a

where;

F represents the force

m represents the mass

a represents the acceleration

    m =

 m =

 m = 63.69 kg

Therefore the mass of the chair is 63.69 kg

electric field is a function of 1/r^2

yes, the force per unit charge for a point charge is inverse square law.
