Answer:5
Explanation:
Given
First Plate has a charge of +Q and area A
Second Plate has a charge of -3 Q and area A
We Know electric Field due to sheet charge is given by

Where Q=charge over the Plate
A=Area of plate
= Permittivity of free space
Electric Field Due to Positive charge will always be away from it while for negative charge it is towards it.
Net Electric Field at a point between between the Plates is the superimposition of two electric with direction


Net electric Field is towards the negative charged plate
The required answer is 66.925 m which is the distance travelled by the car.
B. 60 cm
All parallel light rays are bent through the focal point of a convex lens, so the rays from the flashlight 150 cm above the floor must go through the same point on the principal axis as the rays from the flashlight 120 cm above the floor. The location of the focal point does not change when the position of the object is moved either vertically or horizontally.
Hope this helps !
Since they move down their concentration gradient through a transport protein, they can release energy as a result of chemiosmosis. One example is GLUT1 which moves glucose down its concentration gradient into the cell.
