When a 10-kg block is simultaneously pushed toward the east with 20N and toward the west with 15N, the combination of these forces on the block is 5N toward the East
Let's understand this problem in detail
Let which is in east direction
and which is acting in the west direction
Now,
But and are in opposite direction.
So let's rotate the force vector by 180 degrees which becomes
Now both and are in same directionof the forces are in a single line
Adding both of them, we get
=
= 20N - 15N = 5N, as both of the forces are in east direction hence, the net force is also acting in the east driection

Answer:
C.....im just typing more now because of the rule that it has to be 20 characters long
Answer:
Explanation:
We are given that
d=1.9 cm=
Using 1m=100 cm
We have to find the electric field strength.
Using the formula
Mass of electron,m
Substitute the values
Answer:
a)
b)
Explanation:
Given:
mass of ball,
initial speed of the ball,
mass of the person,
a)
Using the conservation of linear momentum:
When the person catches the ball, assuming that the person catches it with an impact without absorbing the shock.
b)
When the ball hits the person and bounces off with the velocity of .
Using the conservation of linear momentum:
where:
final speed of the ball after collision
final speed of the person after collision
initial velocity of the person = 0
putting the respective values in the above eq.
