Explanation:
Th electric force between charges is inversely proportional to the square of distance between them. It means,

Initial distance, r₁ = 2 cm
Final distance, r₂ = 0.25 cm
Initial force, F₁ = 1 N
We need to find the electric force between charges if the new separation of 0.25 cm. So,

So, the new force is 64 N if the separation between charges is 64 N.
Answer:
a. 2.4 ×109 N ⋅ m2/s
b. 48.3 N⋅s /m2
c. 8.00×104W
Explanation:
See Attached file for explanation
<em>F</em> = 153 N

Explanation:
Let us define first our directional convention. Anything pointing up or to the right is considered positive and anything pointing down or to the left is considered negative. Now let's look at the components
and
:
= 350 N - 200 N = 150 N
= 180 N - 150 N = 30 N
The magnitude of the resultant force <em>F</em> is given by



To find the direction
, we use

or

Answer:

Explanation:
First displacement of the particle is given as
= 11 m at 82 degree with positive X axis
so we can say


resultant displacement of the particle after second displacement is given as
r = 8.7 m at 135 degree with positive X axis
so we can say


now we know that

now we have

so we will have


so angle of the second displacement is given as
