Answer:
Explanation:
From the given information:
Let the first weight be = 80 kg
The weight of the buddy be = 120 kg
The weight of Bubba be = 60 kg
Also, since you and Budda are a distance of 4m to each other, then the length to which both meet buddy will be:
The length of the boat be = 4 m
∴
We can find the center of mass of the system by using the formula:
Answer:
The value is
Explanation:
From the question we are told that
The distance of separation is
The current on the one wire is
The current on the second wire is
Generally the magnitude of the field exerted between the current carrying wire is
Here is the magnetic field due to the first wire which is mathematically represented as
Here is the distance to the half way point of the separation and the value is
