Answer:

F_E = 1797*10^6 N

Explanation:

In order to calculate the electric force between charges q1 and q2 you use the following formula:

F_E=k\frac{q_1q_2}{r^2}

k: Coulomb's constant

q1 = 4*10^6 C

q2 = 18*10^6 C

r: distance between charges in meters = 60 cm = 0.6 m

You replace the values of the parameters k, q1 and q2 in the equation for FE and you obtain:

F_E=(8.98*10^9Nm^2/C^2)\frac{(4*10^6C)(18*10^6C)}{(0.6m)^2}\\\\F_E=1797*10^{24}N

Hence, the electric force is 1797*10^6 N

Объяснение:

Для расчета электрической силы между зарядами q1 и q2 используется следующая формула:

k: постоянная кулона

q1 = 4 * 10 ^ 6 C

q2 = 18 * 10 ^ 6 C

r: расстояние между зарядами в метрах = 60 cm = 0,6 m

Вы заменяете значения параметров k, q1 и q2 в уравнении для FE и получаете:

Следовательно, электрическая сила составляет 1797 * 10 ^ 6 N

Calculate the potential energy stored in a metal ball of a mass of 80 kg kept at a height of 15m from the earth surface.What wil
True [87]

Answer:

39200 joules

the potential energy will be zero

Explanation:

we know that potential energy is found by multiplying mass, acceleration due to gravity and height from the Earth's surface

so it will be

potential energy= mgh

80x9.8x15

= 39200 joules

the potential energy of the mental ball will be zero when kept on the Earth's surface because the height from the Earth's surface will be zero and zero multiplied to any number is zero only

I have a doubt with the second one, this is what I think it is. Consult your teacher if you think my answer for the second one is wrong
