Question

The resultant of 2 forces which have equal magnitude and which act at right angle to each other 1414dyne. Calculate the magnitude of each force ?

Answer 1

Answer:

Explanation:

resultant = √ f1^2+f2^2+2*f1*f2 cos Ф

1414= √2f^2+2f^2cosФ

1414 = √ 2f^2

squaring on both sides

1999396 = 2f^2

f= 999.8  dyne
