Anna rubs two balloons against her hair causing the ballons to become negatively charged. Each of the balloons has a charge of 2.4*10^-6 Coulombs. She holds them a distance of 0.06 meters apart. what is the magnitude electrical force between the balloons?

The magnitude electrical force between the balloons is 14.4 N.

Explanation:

Given that,

Charge on each balloons,

Distance between charged balloons, d = 0.06 m

We need to find the magnitude electrical force between the balloons. We know that two charged particle possess electrical force when placed at a certain distance. The force is given by :

k is the electrostatic constant

So, the magnitude electrical force between the balloons is 14.4 N. Hence, this is the required solution.

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft

find the sum of the two horizontal vectors and the sum of the two vertical vectors
