No ❌Spams❌​

Answer 1

Answer:

force = mass × acceleration

=5 × 2.5

=12.5

Explanation:

C) is the correct answer

Answer 2

Force and acceleration

Let's first write the question properly for a better understanding. Here one word is missing.

$\boxed{\boxed{\begin{minipage}{19em}\textbf{\dag \: \underline{\: Question \:}} \\ \\ \sf\bold{\textsf{The force exerted on a body of a mass 5kg producing an acceleration of \sf{2.5m/s^2} is:}}\\ \\ \sf{A) 7.5N} \\ \sf{B) 2.5N} \\ \sf{C) 12.5N} \\ \sf{D) 5N} \end{minipage}}}$

Force is defined as the product of mass and acceleration of the body. It is represented as F. SI units of mass and acceleration are kilogram and meter-per second respectively. Hence the SI unit of force is kilo-meter per second. This is also called Newton.

Here, we've been given that, The force exerted on a body of 5kg producing an acceleration of 2.5m/s².

With this information, we've been asked to find out the force applied by the body.

We can find out the force applied by the body, by simply using second law of Newton.

Second law of Newton defined as the product of mass and acceleration is equal to the force. In mathematical term it will be like this;

$\implies F = ma$

Where, F is the force applied by the body, m is the mass of the body and a is the acceleration produced by the body.

By using the formula and substituting the available values in it, we get:

$\implies F = 5 \times 2.5 \\ \\ \implies \boxed{F = 12.5 \: N}$

Therefore, the force applied by the body is 12.5 N. So, option (b) is the correct option for this question.
