First you need to draw the picture of the problem to better understand it. Like the one bellow.
In this task you have 2 sides of triangle and we can calculate angle between them. Angle between them is 120 - 35 = 85 degrees.
Once you have those 3 variables you can calculate third side of triangle using cosine law.
a - second displacement
b - first displacement
c- resultant displacement.

now we just need to calculate this.

a = 196
now, we use cosine law again to find the angle between second and first displacement.

degrees
The angle marked with "?" in the graph is our direction angle. We will call it


Second displacement has magnitude of 196 and a direction of -14.64 with positive x axis

Answer:F = kq2/d2 ⇒
q = √(Fd2/k)
q = d √(F/k)
d = 3.8 x 10-10 m
F = 6.4 x 10-9 N
Look up k in your physics book in appropriate units, and plug in the numbers. You should get q in coulombs.
Explanation:
Answer:
F = 489.93 N
Explanation:
I attached an image of the system below.
By using a rotated system of coordinates you have the following equation:
(1)
F: force
Ff: friction force
Wx: x component of the weight = Wxsin(θ)
In this case you have that the speed of the block is constant, then a= 0m/s^2.
You also consider that the friction force is given by:
Wx = μNsin(θ) = μmgsin(θ)
μ: friction coefficient = 0.4
m: mass of the block = 50kg
g: gravitaional acceleration = 9.8m/s^2
θ is the angle of inclination of the inclined plane, you calculate this by using the following:

You replace the values of the parameters in the equation (1) with a = 0m/s^2
