Answer:
Explanation:
According to Newton's second law, we have:
The force of friction is opposite to the motion of the block.
Using the following kinematic equation, we can calculate the distance traveled by the block before it stops().
Solving for x and replacing a from (1):
Answer:
250 cm³
Explanation:
given,
Length of the Box, L = 5 cm
Width of Box, W = 5 cm
height of the box, H = 10 cm
Volume of the Box = L W H
V = 5 x 5 x 10
V = 250 cm³
Volume of the box is equal to 250 cm³
The magnitude of the electrostatic force is 0.09 N, and the force is attractive
Explanation:
The strength of the electrostatic force acting on a charged particle is given by
where
q is the charge
E is the magnitude of the electric field
For the charge in this problem, we have:
is the electric field
is the charge
Therefore, the force experienced by this charge is
And the negative sign means that the force is attractive: in fact, the charge is negative, while the charge that is producing the field is positive (because the electric field points outward), therefore the negative charge is attracted towards the positive charge that is generating the field.
