Quick question plzIf force acting on a body of mass 40kg is doubled. By how much will be the acceleration change? A. By a factor of 2

B. By a factor of 3

C. By a factor of 4

D. remains the same

The new acceleration will be increase by the factor of 2. Hence, option (A) is correct.

Given data:

The mass of body is, m = 40 kg.

We can use the Newton's second law to obtain the result of given problem. As per the Newton's second law, "The force applied by the given object is equal to the product of mass of object and the magnitude of acceleration of object". Then the expression is,

F = ma

a = F/m .....................................................................(1)

Here,

F is the force.

m is the mass.

a is the acceleration.

if the force acting in the mass of body of 40 kg is doubled. Then new acceleration will be,

F' = ma'

(2F) = ma'

2(F/m) = a'

From equation (1) we get,

a' = 2a

Thus, we can conclude that the new acceleration will be increase by the factor of 2. Hence, option (A) is correct.

if i'm not mistaken the answer is A

this is poiselle's equation from fluid mechanic in physics. mech eng

i think the answer is a, hope this : )
