q63 turned out to be easy because the unknowns to me were e and mass of e which turned out to be a fixed variable given at the beggining of the book and 63d it was from right to left i think and in no. 76 the sketch was very easy and it turned out to be zero and in the last question i had to...
my formula for the magnitude of the acceleration is -qEoj/m and j is equal to 0 which will also give me 0 this all seems kinda odd
in c) of the 1st question the formula is (2dm/qEo)^0.5 butall that is given is d
in the 1st question answer a i got 0 because the j component is 0 and the formula is E = -Eoj and 0kind of seems odd for a solution i need someone to confirm it for me
