QAIPMT-2007-Ph-2361: NEET 2007 Physics - Class 12 AIPMT-2007-Ph-2361 Solution: A car moves from X to Y with a uniform speed \(v_u\) and…

A car moves from X to Y with a uniform speed vuv_u and returns to Y with a uniform speed vdv_d. The average speed for this round trip is vu+vd2\frac{v_u+v_d}{2} vuvd\sqrt{v_u v_d} 2vuvdvu+vd\frac{2v_uv_d}{v_u+v_d} vd+vuvdvu\frac{v_d+v_u}{v_d v_u}

Step-by-Step Verified Solution

As the capacitors are connected in parallel, therefore potential difference across both the condensors remains the same. _ Q 1 = C V Q 2 = C 2 V Aslo, Q = Q 1 + Q 2 = C V + Q 2 = 3 2 C V Work done in charging fully both the condensors is given by W = 1 2 Q V = 1 2 _ ( 3 2 C V ) V = 3 4 C V 2
