1 Point The electric field in a region of space is given by E(:c, y) 2 E0 (cos 0:71. i sin 05y), where E0 and a are constants. I (i) Find the electric potential difference V(L,.O) V(O, 0). _ iillf a poSitiVely charged particle qo' is released from rest at the or'igi'n and slides without friction on ' on the m-axis, wh'at'will be its kinetic energy when it reaches the location (17,31) ='(L, 0)
