Answer : The correct option is B- Towards the left.
Solution : Given,
Force on car in upward direction, = 6000 N
Force on car in downward direction, = 6000 N
Force on car in right direction, = 5000 N
Force on car in left direction, = 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 and
are in opposite direction and the force acting on car are same. So, their net force is zero.
And in case of and
, the net force will not be zero because force acting on car are different. The car will accelerate towards left direction because
is higher than the
.
So, the car will accelerate towards left direction.
