an object is moving on a horizontal frictionless surface. if the net force applied to the object in the direction of motion is doubled, the magnitude of the acceleration of the object is
1. halved
2. doubled
3. unchanged
4. quadrupled

Answer :

Answer:

doubled

Explanation:

F=ma1----------(1)

2F = ma2-------(2)

Divide 2nd equation by 1st one

we get a1×2=a2

2. doubled

What is Force?

A force can cause an object with mass to change its velocity, i.e., to accelerate.

[tex]F=m*a[/tex]

Given:

[tex]F=m*a_1[/tex]..............(i)

[tex]2F = m*a_2[/tex]...........(ii)

On dividing equation (ii) by (i)

[tex]\frac{2F}{F} =\frac{m*a_2}{m*a_1} \\\\2=\frac{a_2}{a_1} \\\\a_1=2*a_2[/tex]

Thus, the magnitude of the acceleration of the object is doubled. Therefore, correct option is 2.
