Question

The student gave this solution:

(9.0×109Nm2/C2)(+2.0×104C)(+1.0×104C)/(0.40m)^2

=(1/2)(10kg)v2y+(0.20kg)(9.8m/s2)(10m)

Evaluate the solution to this problem and check all errors you find.

Check all that apply. Check all that apply.

Gravitational potential energy in the second line misses a square for the last factor.

The equation left out the electric potential energy in the second line.

The equation left out the gravitational potential energy in the first line.

Electric potential energy in the first line is not correct.

LHS of the equation representslectric force

RHS should also represent force

hence option a

since you cannot relate force with energy directly gravitational ptential energy misses a square for the last factor
