An athlete swims the length of 50 m pool in 20 s and makes the return trip to the starting position in 22 s. Determine his average velocity in a. The first half of the swim b. The second half of the swim A particle moving in a straight line covers half the distance with [...]

A train accelerates from rest for time t1 at a constant rate a and then it retards at the constant rate b for time t2 and comes to rest. Find the ration t1/t2. A train accelerates from rest for time t1 at a constant rate a and then it retards at the constant rate b [...]

An uncharged parallel plate capacitor is connected to a battery. The electric field between the plates is 10V/m. Now a dielectric of dielectric constant 2 is inserted between the plates filling the entries space. The electric field between the plates now is Potential difference between centre and the surface of sphere of radius R having [...]

A car runs at a constant speed on a circular track of radius 200 m, taking 62.8 s each lap. Find the average velocity and average speed on each lap. A car runs at a constant speed on a circular track of radius 200 m taking 62.8 s each lap. Find the average velocity and [...]

A parallel plate capacitor (without dielectric) is charged by a battery and kept connected to the battery. A dielectric salb of dielectric constant ‘k’ is inserted between the plates fully occupying the space between the plates. The energy density of electric field between the plates will: Potential difference between centre and the surface of sphere [...]
