This diagram shows the forces acting on a car. The center dot represents the car, and the arrows represent the forces acting on
Mariulka [41]

Answer : The correct option is B- Towards the left.

Solution : Given,

Force on car in upward direction, F_1 = 6000 N

Force on car in downward direction, F_2 = 6000 N

Force on car in right direction, F_3 = 5000 N

Force on car in left direction, F_4 = 6000 N

Force : Force is equal to the mass multiplied by the acceleration. The force is directly proportional to the acceleration.

Formula :  F =  m × a

where, F is force, m is mass and a is acceleration.

From the given diagram we conclude that the F_1 and F_2 are in opposite direction and the force acting on car are same. So, their net force is zero.

And in case of F_3 and F_4, the net force will not be zero because force acting on car are different. The car will accelerate towards left direction because F_4 is higher than the F_3.

So, the car will accelerate towards left direction.
