Answer:
Explanation:
electric field between plates
= surface charge density / ε₀
= 108 x 10⁻¹² / 8.85 x 10⁻¹² (ε₀ = 8.85 x 10⁻¹² )
= 12.20 V/ m
Electric potential diff
= electric field x distance between plates
= 12.20 x 17 x 10⁻³ V
= 0.207 Volt
When we double the distance between a source of light and the
surface on which it falls, the amount of illumination on the surface
decreases to <em>one fourth (1/4, 0.25))</em> of the original illumination.

Answer:
Current through circuit will be 
Explanation:
We have given source voltage v = 50 volt
Resistance 
Capacitance 
Time t = 5 sec
Time constant of RC circuit is given by 
We know that voltage across capacitor is given by 

So current will be 
So current through circuit will be 
A. At the top. At this point, the child is highest, and they are not moving. Their potential energy is much greater.
