Answer:
A. The electric field points to the left because the force on a negative charge is opposite to the direction of the field.
Explanation:
The electric force exerted on a charge by an electric field is given by:
where
F is the force
q is the charge
E is the electric field
We see that if the charge is negative, q contains a negative sign, so the force F and the electric field E will have opposite signs (which means they have opposite directions). This is due to the fact that the direction of the lines of an electric field shows the direction of the electric force experienced by a positive charge in that electric field: therefore, a negative charge will experience a force into opposite direction.
Answer:
1.72 x 10³ N.
Explanation:
When a charge is split equally and placed at a certain distance , maximum electrostatic force is possible.
So the charges will be each equal to
31/2 = 15.5 x 10⁻⁶ C
F = K Q q / r²
= 
= 1.72 x 10³ N.

Hey there!
<span>Which statement best summarizes Gregor Mendel’s contribution to science?
Mendel is considered the "father of genetics". He did NOT increse the number of peas </span>
<span>produced by a single plant using cross-breeding techniques, discover grean peas and yellow peas, or invent the green pea by cross-breeding thousands of pea plants.
This means your answer is option D.
Hope this helps
Have a great day (:

Answer:
work done = 500 J
option e is correct
Explanation:
given data
mass = 2 kg
acceleration = 2 m/s
coefficient of kinetic friction = 0.3
block D = 50 m
to find out
work
solution
we know that work done is
work done = f × d ...........1
here f is force and d is block i.e 50 m
so here
force , f - k mg =ma
f = 2 ( 2 + 0.3 ×10 )
f = 10 N
so from equation 1
work done = f × d
work done = 10 × 50
work done = 500 J
option e is correct
