A projectile of mass 1 kg is launched at an angle of 30Β° from the horizontal direction at 𝑑 = 0 and takes time 𝑇 before hitting the ground

Q. A projectile of mass 1 kg is launched at an angle of 30Β° from the horizontal direction at 𝑑 = 0 and takes time 𝑇 before hitting the ground. If its initial speed is 10 msβˆ’1 , the value of the action integral for the entire flight in the units of kg m2sβˆ’1 (rounded off to one decimal place) is ...

An infinitely long wire parallel to the x-axis is kept at 𝑧 = 𝑑 and carries a current I in the positive x direction above a superconductor filling the region

Q. An infinitely long wire parallel to the x-axis is kept at 𝑧 = 𝑑 and carries a current I in the positive x direction above a superconductor filling the region 𝑧 ≀ 0 (see figure). The magnetic  field  π΅βƒ—β†’   inside  the  superconductor  is  zero  so  that  the  field  just  outside  the ...
