Answer:
<h2>7.5 J</h2>
Explanation:
The work done by an object can be found by using the formula
workdone = force × distance
From the question we have
workdone = 10 × 0.75
We have the final answer as
<h3>7.5 J</h3>
Hope this helps you
Here, Fe = Fg
q.E = m.g
We have: E = 360 V
m = 5.4 × 10⁻⁵
g = 9.8 m/s² [ constant value for earth system ]
Substitute their values into the expression:
q (360) = 5.4 × 10⁻⁵ × 9.8
q = 52.92 × 10⁻⁵ / 360
q = -1.47 × 10⁻⁶ [ negative sign represents the nature of charge ]
So, Your Final answer would be 1.47 × 10⁻⁶
Hope this helps!
<h2>The force experienced is 8 x 10⁻¹⁸ N</h2>
Explanation:
When any charge moves into the magnetic field , it experiences the force
The force can be calculated by the relation F = q v B sinθ
here q is the charge and v is its velocity .
B is magnetic field strength and θ is the angle between field and velocity vectors .
Thus F = 1.6 x 10⁻¹⁹ x 200 x 0.5 x sin 30
= 8 x 10⁻¹⁸ N
1 Electrical Potential Energy, separating two charged plates will store energy as the plates want to return to their original position.
<span>2 Spring or Elastic can be stretched to store energy as it wants to return to rest </span>
<span>3 Gravitational energy is stored by moving something (ball or pendulum are both examples of this) against a gravity gradient (lifting an object) that wants to fall back down. </span>
