Answer:
1000 m/s
Explanation:
Given that
Mass of the ball, m = 10 g = 0.01 kg
Charge of the ball, q = 2 C
Field strength of the field, E = 5 N/C
Acceleration of the ball, a = ? m/s²
We know the the equation holds,
F = qE, on substituting, we have
F = 2 C * 5 N/C
F = 10 N
Also, we know that
F = ma, and as such,
a = F / m, on substituting we have
a = 10 N / 0.01 kg
a = 1000 m/s²
Therefore, the acceleration of the ball is 1000 m/s²
The correct answer would be option B. This is because there is 1500g of gas inside of the balloon so if all of the gas escaped then its mass would decrease by 1500g. It couldn't have decreased by less than 1500g because then that would have to mean that all of the gas didn't escape, which it did. If it decreased by more than 1500g then there would have had to be more than 1500g of gas in the balloon to begin with. This is why the answer would be B. 1500g.

The object will fall toward Earth faster. bcz, the Earth got gravity
The centripetal force : F = 293.3125 N
<h3>Further explanation</h3>
Given
mass = 65 kg
v = 9.5 m/s
r = 20 m
Required
the centripetal force
Solution
Centripetal force is a force acting on objects that move in a circle in the direction toward the center of the circle
F = centripetal force, N
m = mass, Kg
v = linear velocity, m / s
r = radius, m
Input the value :
F = 65 x 9.5² / 20
F = 293.3125 N
