Here is a question on A Level Physics that has to be solved by resolving forces to vectors. It is a common mistake in A Level Physics and hopefully helps people on how to solve vector problems.
This type of problem has appeared in all exam boards and can be applied to AQA Physics, OCR A and OCR B, Edexcel, Eduqas WJEC, CIE etc.
It uses Colombo's Law in Electric Fields.
