Answer:
Net electric field,
Explanation:
Given that,
Charge 1,
Charge 2,
distance, d = 3.2 cm = 0.032 m
Electric field due to charge 1 is given by :
Electric field due to charge 2 is given by :
The point charges have opposite charge. So, the net electric field is given by the sum of electric field due to both charges as :
So, the electric field strength at the midpoint between the two charges is 91406.24 N/C. Hence, this is the required solution.
If you neglect air resistance, then you can solve for the horizontal distance using the formula:
dx=vixt
Where:
dx = horizontal distance
vix = initial horizontal velocity
t = time in flight
Now you can see that you have all the given you need.
vix= 2km/h
t = 0.25 hours
We use hours because you need the units to be the same. So just plug that in your equation and you will have your answer:
dx = vixt
=(2km/h)(0.25h)
=0.5km
This means that the answer to your question is B.
Its velocity is 250 per second in the direction of 35 degrees.
Answer:
Centripetal force = 634.6 newton
Explanation:
Given that,
Weight of the automobile, M = 125 Kg
The tangential speed of the automobile, V = 48 Km/h
V = 13.33 m/s
The radius of the circular road, R = 35 m
The centripetal force is given by the relation
Fc = MV²/R
Where M - the mass of the body
V - velocity of the body
R - Radius of its trajectory
Substituting in the above equation
Fc = 125 Kg x 13.33² m²/s² / 35 m
= 22211.11 / 35 newton
= 634.6 newton
Hence, the centripetal force acting on the automobile is 634.6 N
