5m/s 
Explanation:
Given parameters: 
Mass of ball = 0.1kg 
Force on the ball = 5N 
time taken = 0.1s 
Unknown: 
final speed of the ball = ? 
Solution: 
According to newton's second law "the net force on a body is the product of its mass and acceleration".
   Force = mass x acceleration      equation 1
 Acceleration = 
   V is the final velocity 
   U is the initial velocity 
   T is the time taken
  U = O since it is a stationary body; 
       a = 
 
Input "a" into equation 1
   F = m x 
  5 = 0.1 x 
  V = 5m/s

Answer:
The electric field due to the right ring at a location midway between the two rings is 
Explanation:
Given that,
Radius of first ring = 5 cm
Radius of second ring = 20 cm
Charge on the left of the ring = +30 nC
Charge on the right of the ring = -30 nC
We need to calculate the electric field due to the right ring at a location midway between the two rings
Using formula of  electric field
 
 
Put the value into the formula


Hence, The electric field due to the right ring at a location midway between the two rings is
