1 Consider a bob of mass m and having charge q attached to a light string of length 7 and pivoted at point O It is released from rest at an angle 60 with vertical There are two regions Region I left of line PQ has a uniform and constant magnetic field B directed into the plane of paper Region II right of line PQ has a constant and uniform electric field E directed vertically up as shown Consider no effect of gravity in both the regions BQ RAMAN 60 E constant 0 B AYATHE 2ml A Time taken by particle to cross region I for 1st time is f 5qE B Time taken by particle to cross region I for 2nd time is f 5qE C Angular speed of 1 revolution in magnetic field is 2ml D Angular speed of 2nd revolution in magnetic field is 2ml 13qE 13qE ml
