The acceleration of the charge is 1.07 × 10²⁸ m/s². It is obtained as the force per unit mass of the charge.
<h3>What is Columb's law?</h3>The force of attraction between two charges, according to Coulomb's law, is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.
The electric force is found as;
The acceleration of the charge is found as;
Hence,the acceleration of the charge is 1.07 × 10²⁸ m/s².

Answer:
The angular speed of rolling ball is 3.23 rad/sec.
Explanation:
Given that,
Radius = 1.95 cm
Speed = 6.30 cm/s
Suppose, we need to find the angular speed of rolling ball
We need to calculate the angular velocity
Using formula of angular velocity
Where, r = radius
= angular velocity
Put the value into the formula
Hence, The angular speed of rolling ball is 3.23 rad/sec.
Answer:
3.75 m/s^2
Explanation:
The centripetal acceleration of an object in uniform circular motion is given by the equation:
where
v is the tangential speed of the object
r is the radius of the trajectory
In this problem, r = 60 m and v = 15 m/s, therefore the centripetal acceleration of the car is
