The magnitude of the force causing this acceleration is 15 N
<u>Explanation:</u>
we know that
F=ma: According to the newton's second law
F - force acting on the object
m - mass of the object
a - acceleration
Newton's second law states that acceleration depends on force acting on the object and mass of the object.
Force is directly proportional to acceleration and mass is inversely proportional to acceleration.
here,
m = 5 kg
a = 3 m/s2
![F = m \times a\\F = 5 \times 3\\F = 15 N](https://tex.z-dn.net/?f=F%20%3D%20m%20%5Ctimes%20a%5C%5CF%20%3D%205%20%5Ctimes%203%5C%5CF%20%3D%2015%20N)
Elements in the same group in the periodic table have similar chemical properties. Hydrogen and Lithium, who both belong to alkali metal group, have the same chemical properties.
