Answer:
(a). The electric potential at 1.650 cm is 
.
(b). The electric potential at 2.81 cm is 
.
Explanation:
Given that,
Radius of sphere R=2.81 cm
Charge = +2.35 fC
Potential at center of sphere
(a). We need to calculate the potential at a distance r = 1.60 cm
Using formula of potential difference
The electric potential at 1.650 cm is .
(b). We need to calculate the potential at a distance r = R
Using formula of potential difference
The electric potential at 2.81 cm is .
Hence, This is the required solution.
Power is equal to the rate of energy usage, or work over time (W/t). It could also be consider Fd/t, since W=Fd.
Answer:
999 V
Explanation:
Charge deposited on the capacitor
= current x time
= 2 x 10⁻³ A x 5 x 10⁻³
= 10⁻⁵ C
increase in volt = charge deposited / capacitance
10⁻⁵ / .1 x 10⁻⁶
= 10² V
= 100 V
voltage in the beginning = -1 V
voltage at the end
= -1 + 100
99 V .
Insulators- fur, plastic, lots of non metals
Conductors- metals, wire, most metals

Answer:
Pluto
because the the gravitation strength is small, so it will be accelerating slow
