Answer:
c = 3.00E108 m/s = 3.00E5 km/s
t = S / v = 3.84E5 / 3.00E5 = 1.28 sec
Static current is an imbalance of electric charges within or on the surface of a material,however electric current is electric charge on motion.
Answer:
option (b)
Explanation:
Let the electric field is given by E.
mass of proton = mp
mass of electron = me
acceleration of proton = ap
acceleration of electron = ae
Charge on both the particle is same but opposite in nature.
The force on proton = q E
The force on electron = - q E
acceleration of proton, ap = q E / mp
acceleration of electron, ae = - q E / me
We observe that the force is same in magnitude but opposite in direction, acceleration is also different and opposite in direction.
