The correct answer to the question is : A) Tossing it horizontally at a faster speed.
EXPLANATION:
Before going to answer this question, first we have to know the horizontal distance covered by any body when it is fired parallel to the ground.
Let us consider a body of mass m is fired with velocity u parallel to the ground. Let it was projected at a height h from the ground.
Hence, the horizontal distance covered by the projectile is calculated as -
Horizontal distance R = .
Here, g is known as the acceleration due to gravity.
From above, we see that more is the initial velocity, the more is the horizontal distance covered by it i.e the more is the widest curved path.
Hence, the correct answer to the question is that tossing a ball horizontally at a faster speed will trace out the widest curved path.
As per Newton's II law we know that
here
F = applied unbalanced force
m = mass of object
a = acceleration of object
now it is given that force F = 50 N North applied on block on earth due to which block will accelerate by 4 m/s^2
so here from above equation
Now we took another situation where block is placed on surface of moon and again force F = 25 N is applied on the block
So we will again use Newton's II law
so block will accelerate on moon by acceleration 2 m/s^2
