<u>Answer:</u>
The velocity of the truck is 34 m/s.
<u>Explanation:</u>
The momentum (p) of an object is the product of its mass (m) and its velocity (v) which can be written as:
<em>p = mv</em>
Here in this problem, we are given a truck which has a momentum of 40120 kg and a mass of 1180 kg and we are to find its velocity.
So substituting the given values in the above formula to find the velocity of the truck.
Truck's velocity = = 34 m/s.
Answer:
Explanation:
It is given that,
The radius of the solid sphere, R = 50 cm = 0.5 m
Charge on the sphere,
We need to find the magnitude of the electric field r = 10.0 cm away from the center of the sphere. The electric field at point r away form the center of the sphere is given by :
So, the electric field 10.0 cm away from the center of the sphere is . Hence, this is the required solution.
