Answer:
The diameter of the circular path decrease
Explanation:
The magnitude of the magnetic force exerted on the proton is given by:
According to Newton's second law, this force is equal to the centripetal force. Therefore, we have:
Recall that . Replacing and solving for B:
Thus, the field stregth is inversely proportional to the radius of the path and since the radius is directly proportional to the diameter, if the field strength increases, the diameter decreases.
Answer:
3.1468 sec
Explanation:
We have given the speed of the car is 65 miles/hour
The distance traveled by the car = 100 yards
As it is given that 1 yard = 3 feet
So 100 yard =100×3=300 feet
As in question it is given that 1 mile =5280 feet
So 300 feet
Now time taken
