A 1.0 kg object is attached to a string 0.50 m. It is twirled in a horizontal circle above the ground at a speed of 5.0 m/s. A b

all is moving on a circular path. The ball is currently at the top right position of the circle. Point a is above and to the left of the ball. Point b is above and to the right of the ball. Point c is down and to the right of the ball. Point d is down and to the left of the ball and inside the circle near the center. What is the magnitude of the centripetal force acting on the object? 2.5 N 10. N 25 N 50. N

<span>50 N The centripetal force upon an object is expressed as F = mv^2/r So let's substitute the known values and calculate F = mv^2/r F = 1.0 kg * (5.0 m/s)^2 / 0.5 m F = 1.0 kg * 25 m^2/s^2 / 0.5 m F = 25 kg*m^2/s^2 / 0.5 m F = 50 kg*m/s^2 F = 50 N So the answer is 50 N which matches one of the available choices.</span>

A point charge Q is located a distance d away from the center of a very long charged wire. The wire has length L &gt;&gt; d and
zzz [600]

Answer:

F = \frac{Qq}{2\pi \epsilon_0 L d}

Explanation:

As we know that if a charge q is distributed uniformly on the line then its linear charge density is given by

\lambda = \frac{q}{L}

now the electric field due to long line charge at a distance d from it is given as

E = \frac{2k\lambda}{d}

E = \frac{q}{2\pi \epsilon_0 d}

now the force on the other charge in this electric field is given as

F = QE

F = \frac{Qq}{2\pi \epsilon_0 L d}
