Correct option is C
The correct answer is (c) 35 J
In physics, work is defined as the product of the force applied to an object and the distance over which the force is applied in the direction of the force.
Work=Force×Distance
Unit: The SI unit of work is the joule (J).
Given: Force = 7 N and Distance = 5 m
Substituting the values into the formula:
Work=7N×5m=35J
Therefore, the work done is 35 joules (J).
Facts to remember:
Force is a vector quantity that represents the interaction between two objects, resulting in a push or pull. It causes objects to accelerate or deform.
Unit: The SI unit of force is the newton (N).
Distance is a scalar quantity that measures the extent of space between two points. It is the total path length traveled by an object.
Unit: The SI unit of distance is the meter (m).
