The rate at which a force displaces a mass a horizontal distance is measured in?
1 answer:
Answer:
c. joules
Explanation:
The rate at which a force displaces a mass a horizontal distance is measured in joules. In science, this phenomenon is known as work done.
Work done can be defined as the rate at which a force acting on an object or a body causes it to experience a displacement. The work done is a scalar quantity and is measured in joules (J).
Mathematically, work done is given by the formula;
Work done = force * distance
Where,
- W is the work done
- F represents the force acting on a body.
- d represents the distance covered by the body.

Explanation:
Given that
Speed ,v= 2 x 10⁵ m/s ( - y direction)
B= 0.6 T (- z direction)
The resultant force on the proton given as
F= m a
For uniform motion acceleration should be zero.
F = 0
Electric filed should be apply in the negative x direction.
