5. A long straight conductor AB carries a current of 3
En conductor AB carries a current of 3A. A proton P travels at 5 x 10 m/s parallel to
wire 0.3 m from it and in a direction opposite to the current as shown in the figure. Calculate
the force which the magnetic field due to the current carry
he magnetic field due to the current carrying wire exerts on the proton. Also give
its direction

Explanation:
Gondwana 420 million years ago. View centered on the South Pole.
Gondwana ( /ɡɒndˈwɑːnə/),[1] (or Gondwanaland),[2] was a supercontinent that existed from the Neoproterozoic (about 550 million years ago) until the Jurassic (about 180 million years ago).
It was formed by the accretion of several cratons. Eventually, Gondwana became the largest piece of continental crust of the Paleozoic Era, covering an area of about 100,000,000 km2 (39,000,000 sq mi).[3] During the Carboniferous Period, it merged with Euramerica to form a larger supercontinent called Pangaea. Gondwana (and Pangaea) gradually broke up during the Mesozoic Era. The remnants of Gondwana make up about two thirds of today's continental area, including South America, Africa, Antarctica, Australia, Indian Subcontinent and Arabia.
The formation of Gondwana began c. 800 to 650 Ma with the East African Orogeny, the collision of India and Madagascar with East Africa, and was completed c. 600 to 530 Ma with the overlapping Brasiliano and Kuunga orogenies, the collision of South America with Africa and the addition of Australia and Antarctica, respectively.[4]
