What is the net force on this object?
2 answers:
Answer:
200N
Explanation:
The net force or resultant force on the object is obtained by adding all the forces acting on it.
In this case we have an upward force and a downward force, since they go in different directions they must have a different sign: we will define upward as positive and downward as negative:
The sign only to indicate that they are going in opposite directions, so the resulting force:
The net force acting on the object is 200N. (downwars due to the negative sign).

Answer:
4.53 kg
Explanation:
spring constant, K = 16 N/m
Amplitude, A = 20 cm = 0.2 m
Maximum speed, v = 37.6 cm/s = 0.376 m/s
The formula for maximum speed is given by
v = ωA
where, ω is the angular frequency
0.376 = ω x 0.2
ω = 1.88 rad/s
m = 4.53 kg
Thus, the mass of banana bunch is 4.53 kg.
Given :
An electron moving in the positive x direction experiences a magnetic force in the positive z direction.
To Find :
The direction of the magnetic field.
Solution :
We know, force is given by :
Here, q = -e.
Now, for above condition to satisfy :
So,
Therefore, direction of magnetic field is negative y direction.
Hence, this is the required solution.
