About the video:
This is the part 4 of Concept with Questions by Let's Improve . In this video we have discussed some numerical questions of One Dimensioanl Motion and Relative velocity of Class 11 physics in Bengali . This video of numerical questions contain numerical question of various dificulty level for JEE , WBJEE , NEET and otrher competetive exams . I hope these series of physics numerical questions in Bengali will help you in various competetive exams . In this video we have explained numerical questions on relative velocity , boat river numerical questions , motion of boat in river of class 11 physics in bengali.
