Answer:
(a) The current in the wire is 19.89 A
(b) The distance from the wire is 0.159 cm
Explanation:
Given;
magnetic field, B = 2.5 mT
diameter of the wire, d = 1 cm
radius of the wire, r = 0.5 cm = 0.005 m
(a) The current in the wire is calculated as;
(b) The distance from the wire where the magnetic field is 2.5 mT is calculated as;
Answer:
Distance, d = 8 meters
Explanation:
Given that,
Initial velocity of the motorboat, u = 7 m/s (west)
Final velocity of the motorboat, v = 2.4 m/s (west)
Acceleration of the motorboat, (east)
We need to find the distance covered by it. It can be calculated as :
s = 8 meters
So, the distance covered by the motor boat is 8 meters. Hence, this is the required solution.
