Question

b) Rahul pulls a block by a force of 10 units whereas Kishan pulls a block by a force of 6
units from the opposite side. What is the net force acting on the block?​

Answer 1

Answer:

Net force = 10-6

4 unit

So net against the block is 4unit

Answer 2

Concept:

• Force is a push or a pull on an object
• It causes a body to start motion, continue moving or bring it to a rest
• More than one force can act on an object at a time
• In cases where multiple forces are present, we need to consider the directions of the forces

Given:

• Force applied by Rahul F₁ = 10N
• Force applied by Kishan F₂ = -6N
• We have taken the direction of F₁ to be positive
• Since F₂ is acting in the opposite direction, we take its direction to be negative

Find:

• The net force that acts on the block

Solution:

The net force acting on a block is the summation of all forces acting on it

F = F₁ + F₂

F = 10 + (-6)

F = 4

• The answer that we get is positive.
• We had taken the direction of the force applied by Rahul to be positive
• The net force acts in the direction in which Rahul pulled the block

The net force acting on the block is 4N.
