Question

Applying a force of 30 N on an object produces an acceleration of 2 m/s2

. Find force​

Answer 1

Answer:

Correct Question

Applying a force of 30 N on an object produces an acceleration of 2 m/s2Find mass

Given

Force = 30 N

acceleration= 2m/sec²

To find

mass of the body= ?

solution

➠According to Newton's second law of motion

$\boxed { \bold{f = m.a}}$

where

• f= force
• m=mass
• a= acceleration

Now substitute the values in the above formula

⇝mass = force /acceleration

⇝ mass = 30/ 2

⇝ mass = 15 kg

✿so if 30 N of force is applied on a body of mass 15 kg then it will move with the Acceleration of 2m/sec².

Answer 2

Correct Question :

Applying a force of 30N on an object produces an acceleration of 2m/s². Calculate mass of the body.

Solution :

Given that,

• Applied force = 30N
• Acceleration = 2 m/s²

We are asked to find mass of the body.

❖ As per newton's second law of motion, force is defined as the product of mass and acceleration.

Mathematically, F = m a

• F denotes force
• m denotes mass
• a denotes acceleration

By substituting the given values;

➙ F = m a

➙ 30 = m × 2

➙ m = 30/2

➙ m = 15 kg

Knowledge BoosteR :

• Force is a polar vector as it has a point of application.
• Force can be classified as positive and negative.
• A positive for e represents repulsion and a negative force represents attraction.
• SI unit of force : N
• It has both magnitude as well as direction$.$
