Expert Solution
To determine
The magnitude of the force applied horizontally.

Explanation of Solution

Given info: The work done by the student is 400Â J in moving a desk by a distance of 2.0Â m .

Explanation:

Formula to calculate the work done is,

W=Fd

Here,

W is the work done

F is the force

d is the distance

Substitute 400Â J for W and 2.0Â m for d
