Answer:
a) 74.8 V/m
b) direction -(i)
Explanation:
For this case, the electric field is defined as:
because V is a function dependent of x so we can derivate it:
so:
Because of the sign, the magnitude of electric field 74.8 V/m on the negative direction of i vector, thus means towards the plate 1.
Answer:
a)
b)
Explanation:
Given:
mass of the container,
displacement of the container,
Since the load is lifted using cable there will be weight acing downwards and the tension in the cable will act upward which will be equal in magnitude to the weight.
So,
(upwards)
Now the work done by the tension:
Now the work done by the gravity:
since displacement is in opposite direction to the gravity
Ur answer is 3 and i'm sure of it
Answer:
6.28 m/s.
Explanation:
Given that,
The mass of the object, m = 0.2 kg
The radius of the circle, r = 0.5 m
It takes the object 0.500 s to complete one revolution.
We need to find the translational speed of the object. Let it is v. We know that,
So, the transalational speed of the object is 6.28 m/s.
