Answer:
The total charge on the rod is 41.18 nC
Explanation:
Given;
length of glass rod, L = 10 cm = 0.1 m
radius of the rod, r = 4 cm = 0.04 m
Force of repulsion = 940 μN = 940 × 10⁻⁶ N
Charge on the bead = 6.5 nC = 6.5 × 10⁻⁹ C
Charge on the rod, Q = ?
From coulomb's law;
Where;
F is the force of repulsion in N
q₁ and q₂ are the charges on the bead and rod
R is the resultant distance between the two charges;
K is coulomb's constant = 8.99 x 10⁹ Nm²/C²
Therefore, the total charge on the rod is 41.18 nC
As per Newton's law of inertia we can say every object will move in its state of motion either in the state of rest or will move with same constant velocity until some unbalanced external force will act upon it
so here we have to fill the space which says that stationary object can start or moving object will change its direction only in which case
so here the correct answer should be Unbalanced Force condition we will obtain such situation.
so we have
<u>Unbalance force</u> can cause a stationary object to start moving or a moving object to change its speed or direction or both.
