Answer:
140 N-m
Explanation:
Work done is equal to the product of force and displacement
Here in this case,
Force = weight of the cart
Displacement = distance moved by the cart
Work done = Force x displacement
= 35 N x 4 m
= 140 N-m
Answer:
a. Electric field lines can never cross each other.
d. Wider spacing between electric field lines indicates a lower magnitude of electric field.
Explanation:
a. The electric field lines cannot be crossed, since this would mean that there would be more than one electric field vector for the same point at the place where the crossing occurs.
d. The space between the field lines is inversely proportional to the intensity of the electric field.
