Here is your answer
C. towards the floor
REASON:
Using Fleming's Left hand rule we can determine the direction of force applied on a moving charged particle placed in a magnetic field.
The direction of current will be just opposite to the direction of electron(negative charge) because current moves from positive to negative terminal whereas electron moves from negative to positive terminal.
So, direction of current- North to South
Now applying Fleming's Left hand rule we get the direction of force in downward direction, i.e. towards the floor.

The density of hematite ore is <u>4.78 g/cm³</u>.
Let the mass of the ore be m₁ , the volume of the flask <em>V</em>, total mass of water and ore M, mass of water be m₂, density of ore ρ₁ and the density of water be ρ₂.
Density of a substance is defined as the mass per unit volume.
The mass of water in the flask is given by,
Calculate the volume V₂ of the water in the flask.
Calculate the volume V₁occupied by the ore in the flask.
1 ml is equivalent to 1 cm³.
Calculate the density of the ore.
The density of the hematite ore is found to be 4.78 g/.cm³
Answer:
0.381 m
Explanation:
Distance traveled S is found by
Where S is distance traveled, u is initial velocity, t is time, a is acceleration
Since we acceleration a is given as 60g, where g is gravitational constant of 9.81 then a=60*9.81=588.6
The initial velocity u is zero hence ut=0
Substituting a with 588.6, t with 36 ms
S=0.381 m
