Explanation:
Below is an attachment containing the solution.
Explanation:
the question it's not complete as I don't know the height as the formula for potential energy is : <u>PE = </u><u>mgh</u>
<em>(m) - mass acceleration due to gravity </em>
<em>(g) - acceleration due to gravity </em><em> </em><em>(</em><em>9</em><em>.</em><em>8</em><em> </em><em>m</em><em>/</em><em>s2</em><em>)</em>
<em>(h) - height</em>
Answer:
1782.7 N/C, downward
Explanation:
Since the charged sphere is in static equilibrium, it means that the electric force acting is balanced with the weight of the sphere, so we can write:
where
m = 3.62 g = 0.00362 kg is the mass of the sphere
g = 9.8 m/s^2 is the acceleration of gravity
is the magnitude of the charge
E is the magnitude of the electric field
Solving for E,
In order for the sphere to be in equilibrium, the electric force must be in opposite direction to the weight, so the electric force must point upward. Since the sphere has a negative charge, the electric field has opposite direction to the electric force: so, the electric field direction is downward.
It seems you didnt give the last answer, but a - d seem like pretty reasonable things to do so it is probably C.
