Answer: The correct option is A ( horizontally towards the east)
Explanation:
Magnetic field is a region around a magnet or a current- carrying conductor, where a magnetic force is experienced. The magnetic effect of electric current was first discovered in the early 1820 by Oersted. Using a wire that had current flowing through it and a pivoted magnetic needle, he discovered that the direction of deflection depended on the direction of the current and whether the wire was above or below the needle.
From the way the needle turns when current when current carrying wire is held parallel to it, he therefore concluded that:
--> a current has magnetic field all round it,
--> the magnetic field is in a direction perpendicular to the current.
The above discovery was now modified in Fleming's left hand rule which states that when conductor carrying current is placed in a magnetic field, the conductor will experience a force perpendicular to both the field and the flow of current.
Therefore from the question, a vertical wire carrying current in DOWNWARD direction is placed in a HORIZONTAL magnetic field directed to the NORTH. The direction of the force on the wire is to the EAST.

<h2>Answer:</h2>
All the energy sources are correctly matched with their category.
Explanation:
Renewable energy sources:
These are energy sources which can be replenished as they don't in involves the irreversible phase change.
These resources can never be ended as they can be used again and again.
Wind, geothermal, biomass, bio gas are example of renewable energy sources.
Non renewable energy sources:
These are the energy source which can never be replenished after one time use. They undergo the chemical irreversible change.
These sources are lacking with the passage of time because they can never be reused.
Oil, gas, coal and natural gas are examples.
