A dynamometer D, which is a device used to measure force, is attached to two blocks of masses 6 kg and 4 kg. Forces of 20 N and 10 N are applied on the blocks as shown in the figure. The reading of the dynamometer is
Text Solution
Verified by ExpertsThe correct answer is:
D
14 N
Make a free body diagram then write force equation for the blocks involving spring force.
20 - T = 6a
T - 10 = 4a
a = l and T = 14 N
