What are the magnitude (size) and direction of the cumulative force acting on the car shown in the picture a. 30 n to the right b. 2500 n down c. 30 n to the left d. 3500 n up

30n to the right

Explanation:

The correct answer is option(A).

Explanation:

Total forces exerting on the car = F

= Force on car exerting in right direction

= Force on car exerting in left direction

= Force on car exerting in upward direction

= Force on car exerting in downward direction

(negative sign shows the direction)

Since, upward force are equal in magnitude but opposite in direction by which they will balance out each other.so, the net force car will be due to two forces and

(negative shows the direction)

The magnitude (size) and direction of the cumulative force acting on the car will 30 N towards right direction.Hence, correct answer is option(A).

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.
